WTC7 Simulation Evaluation - World Trade Center 7 Collapse Research Study
Vložit
- čas přidán 12. 09. 2024
- Simulated with completely new developed software designed for structural simulation, this revision of the old WTC 7 simulation attempt serves as validation case for the BCB software.
New in this simulation compared to the old one:
- Multiple constraints per connection are used to represent individual degrees of freedom (DOF)
- Breaking thresholds are computed from real world parameters
- Correct steel thicknesses and beam dimensions are used
- Plastic deformation is now simulated
While this simulation of World Trade Center 7 is still not 'perfect' it resembles much better the specific characteristics observed in the documentation of reality than the older model. This simulation confirms mostly the findings of NIST, it is safe to say that the columns 79 to 81 were the first columns which gave way because the removal of other columns led to much different collapses. More than that is hardly determinable, such a system behaves just to chaotic to tell what exact connection failed first. In this regard NIST might be wrong by declaring a specific failure point. However, I consider this not being an important question given the fact how compromised the structure around these three columns must have been exposed to fire for hours, a situation beyond any imaginable safety design specification.
Having said that, I want to emphasize that this video is not intended to prove or disprove 9/11 conspiracy theories. I'm deleting comments that include hate speech, so you better think twice before starting an argument about the reasons of 9/11 here. Instead, I recommend to read a neutral source like: en.wikipedia.o... to get some pros and cons instead of watching CZcams videos.
This is a private project. There are no third parties involved. There is no scientific report available. No peer review has taken place. Thanks for watching.

Jesus Christ what’s up with the mania of “truthers” in the comment section. It seems like the majority of y’all can’t even argue actually factual information and choose to blindly follow random people on the internet who clearly are pseudo-intellectuals with 0 logical reasoning whatsoever instead of actually taking the time to look at officially published reports, witness statements, or just general knowledge on how structural collapses work.
And I hate to say this again but an opinion is not a factual statement, therefore, stop making baseless claims about “cOnTroLlEd dEmOlItIon” when it’s VERY obvious that you have no logical reasoning or any evidence-citing skills whatsoever.
Oh and the evidence that you try to prove your already baseless claim literally contradicts everything you just said.

Wtc7 is the first building in the history that collapsed due to sadness
Oh
It couldn’t stand its brothers dying so it had to die too
Actually it was a hate crime, it didn't want any chance of any Muslims taking it down so killed itself
Yeah, although it was like the first tower which stood so strong after initially being struck suddenly lost it's will to live after it's twin in Tower #2 literally bit the dust, considering it too went down a half hour later.
Or will it have been out of sympathy, who knows. At least it wasn't because of fire.
I saw a lot of videos on World Trade Center 7 on the day it happened... This is not at all how it fell. It came straight down.
Exactly, it fell perfectly straight down into it's own footprint, as it should in a controlled demolition. It did not topple off to the side as in this BS simulation. Anyone with an analytical mind who spends time looking into the events of this day emerges a changed person.
@@davidroscoe3815 no, not even a controlled demolition can do that. Where’s your common fucking sense?
@@davidroscoe3815 I was definitely a changed person.
@@davidroscoe3815 So correct David---this was a crime scene. If people just study this with a little independent thought you will see, just by looking at the video and the sounds this was a planned, controlled demolition. Silverstein said he told the fire department to 'pull' the building because there was so much loss of life that day--that was the least he could do. And by the way, Silverstein missed his 8 am breakfast meeting in Tower 1 the day of 911; he never missed a breakfast up on the Windows of the World, except that day-he had an 8 am dermatologist appointment, because you know how those dermatologist have those 8 am appointments. Still his daughter that was suppose to meet him there that day to meet clients also didn't make it, but she did not have a dermatologist appointment; she just decided not to go; but the clients made it unfortunately. Its a classic free fall velocity speed and controlled demolition. The charges were set (and heard going off in sequence by fire fighters and on video) at 5 PM column by column so that there was no resistance below each floor. You can see the Penthouse collapse first on the top floor onto itself and then the other floors follow. How could columns on 3 and 4th floor cause the penthouse to collapse first at the top. Its ridiculous---the model doesn't match the video---maybe they should watch the video first and then create the model of how it collapsed. I checked the seismic activity in the area and nothing-----so maybe we may want to review this a bit.
It’s literally coming straight down in this video lol
Who made this film, Silverstein productions?
Yes, and they're coming for you
Could be. He made enough profit with the Insurance policies he took out just before 911 to fund this crap. He probably pays the nameless trolls too that try and sell the Column 79 domino explanation you see here. NIST originated it and it took seven years for them to cook up this crock.
Aparently it was M Fitz ^^^^
of course!
The maker of this video has not a clue what he is talking about either which is hilarious.
this was my Daddy's building. he is still here with us today, he made it out in time.
That's good to hear. We had so many amazing stories of friends who survived because of strange situations - like a friend who would have been just above the impact point but he had to wait for a plumber that day. Someone should make a documentary about all those stories.
I'm glad to hear that your father made it and by the way you are beautiful
Did anyone die in #7? I never remember hearing about that.
@@Lisapreps according to barry jennings he stepped over bodies. He was also killed
@@Lisapreps No, I think everyone was out before. But there's witness of explosions who was trapped but escaped. He died before he could witness though.
Why do demolition company need explosives when all they have to do is set a fire and damage a few steel beams! Then wait for a few hours!
The collapse of Building 7 damaged 30 West Broadway across the street beyond repair. It had to be torn down. It also caused a billion dollars in damage to the Verizon Building next door which took 3 years to repair. Steel framed buildings in urban areas are dismantled, not explosively demoed for that reason.
But they used magic fire which is much stronger than your ordinary everyday fire. Magic fire can cut right steel and burn under ground without air for a three months. Didn't you know that!

This doesnt even remotely resemble the actual collapse.
How do you mean? See, you truthers always negate but rarely spend the time explaining your belief. According to vids of wtc 7 I've seen, it does match.
well, it's hard to see what the building looks like in real life while its collapsing because there's dust everywhere from two other collapsed buildings along with dust being created from parts of the collapsing building getting disintegrated. Also, I think it does look pretty accurate, as the first clip of this video shows.
czcams.com/video/8WNk674LZrI/video.html
As you can see, part of the top falls in several seconds before the rest of the building does, which indicates that the actual "building" part of the building is collapsing on the inside while the outer walls remain standing. You can even see the floors of the building collapse through the windows, I find this collapse quite interesting that even though the building has already begun to collapse, it's not obvious to somebody watching for several seconds.
@@tudorjason None is more blind than those who will not see. Please post a google search showing building 7 twisting and falling over. I'll go first; google video, 'WTC Building 7 collapse.' And, please, don't post a link to a computer-generated lie such as the one above.
@@kermitthemutantlevitatingf7836 That you see dust obscuring 'building, 7' proves that whatever it is you are looking at, it is most definitely NOT building 7.
@@inkblot131 ? I'm talking about the collapse creating dust, which obstructs other parts of the building, just like you see when the twin towers collapsed earlier, the parts of the building actually breaking apart are obstructed by dust that is created from pieces disintegrating. Simulations normally don't add in the dust so you can see the parts breaking apart. As for the actual video, it is very clear that the building collapsing is 7WTC
This doesn’t match the footage
Of course it doesn't. It's a model. But the initiation through progression mechanisms do and that is what actually matters, not what the exterior moment frame was doing 10 seconds later.
Isn’t it funny you can only find simulations now and one video that shows the collapse but says it was “due to fires”
It matches the collapse the black thing collies first then the tower collapsed

Also funny how the emotional blackmail pinned comment at the top of this video doesn’t allow people to reply and it mainly similarly written emotional replies devoid of actual facts. They’re trying to get us to shut up about it but we never will.
The mental gymnastics required to rationalize #7 perfectly collapsing due to some small fires and superficial damage, is more impressive that the feat itself.
How do you define "perfectly"?
How do you define "small fires" and how does that compare to the actual fires reported in the real world event?
How do you define "superficial" and how does that compare to the actual damage Building 7 is known to have suffered.

"World trade center 7 is the first known instance of a tall building falling primarily due to fires"
The explanation given is weak and unsupported by evidence. As unsubstantiated as controlled demolition is in your opinion, the official story will always be less supported by evidence. I was part of those who believe the official conspiracy for a long time until I took a good hard look at the evidence, realizing there isn't any. Then I actually took the time to play devil's advocate and look into the evidence for conspiracy, it became obvious very quickly that I had been duped into putting blind faith in the official report. Simply does not stand up to basic scrutiny.
Honest question with wish for honest answer: is'nt it inaccurate to simulate it with the building beeing completely empty. The weigh should be of because there was furniture in it and also in this simulation there are things missing from the building like the heavy elevator and walls inside the offices
Nevertheless this is amazing work I just mean this as constructive feedback
This is true, adding live load is a desirable target for future revisions. This requires a bit more research and there are still some deficits in the software to deal with too. But the first large step is done.
Kostack Studio thanks for the quick answer. Great work!
I really believe your splitting hairs with that comment.
hahahahhaha Furniture???! dude, thats like the weight of the flees on a dogs back.. it would not matter
*Sigh* go watch the video footage of building 7 collapsing again, and when you generate a simulation that actually matches what we see in the footage, let me know. This looks nothing like the footage of the collapse
Right. New examination prove NIST is LYING. watch this: czcams.com/video/Xd7tqpwdlpQ/video.html
It's way closer than NIST's simulation
@CoolNerd04 No. WTC 7 was there until 5:22 pm. and there was no substantial damage to WTC 7 to start a "flip flop" damage that NIST blames on column 79. Keep in mind also that BOMBS went off in WTC 7's lobby before the south tower (that exploded first) wen down. This is according the Mr. Hess and Barry Jennings who escaped from the building before all of this happened.

Nice computer graphics, but still does not look anything like the real collapse footage taken on the day. WTC 7 neatly collapsed into its own footprint and hardly touched the buildings along side it. Also, where are the elevators and stair wells?
@12weasel100 How would elevators and stair wells affect the results? Are you kidding me? They are some of the strongest parts of a building. You obviously don't know anything about architecture and engineering. The actual footage of the collapse shows the building falling straight down into its footprint. This computer simulation does not. It falls sideways and collapses on to another building. That did not happen on 9-11.

My first impression when I saw these towers go down was similar, "Were they held up by jelly?" I instantly knew there is NO WAY two tiny (by comparison) planes in contrast to these huge buildings was going to make them fail from top to bottom.
it went straight down, it didn't flop over
why so agressive
The Only True Orange - Absolutely. But duhplunkers think the animation is right and the real thing is wrong. Duhplunkers are special.
Kathryn Harris - Nobody cares if building 7 leaned to the south "towards the end". No surprise considering it's damage on that side. Many regular demolitions lean somewhat, particularly near the end (check them out). What building 7 didn't do, is flop over to the east. The Only True Orange is correct.
schmui It did Not fall. Completely straight down, it fell down at a slight angle, the east side leaning north and the West side leaning slightly to the south

i noticed that too,
instead we will be left with BS simulations which "fit the narrative"
get f**ked
Was wtc7 made out of match sticks?
Popsicle sticks. Lol.
And dominoes, yes. No glue though, that would make for a rather sturdy structure, that's cheating.
So I'm a bit confused here:
- How did you simulate the initial "collapse"? As in did you simulate softening of the steel by fires on the lower floors?
- How does a lower floor collapsing make all the floors above it collapse? Does a floor collapsing rip apart the nearby structural column or what?
- How likely is a building of this size to collapse this neatly due to the damage mentioned above?
-This model is agnostic as to initiating mechanism. For the purposes of the model it does not matter of that mechanism was fire, corrosion, metal fatigue, gross overloading, midgets with saws, harsh language or hush-a-boom sooper sekrit non-exploding explosives.
-Sections of one floor, dropping 14 feet onto the floor below which was not designed for that gravity load will cause it to fail, joining the mass of falling debris down to the next, rinse and repeat. Remove enough floors and the column they are attached to will lose sufficient lateral support that it will buckle. If that column happens to be one which carries a disproportionate share of the gravity load for the structure due to the structures highly unusual design and load carrying requirements,...
-100% likely since it actually happened.
@@MFitz12 Ok, thanks for the answers!
Also, what was so "unusual" about WTC7's design and load carrying requirements? I did read that it had a bigger footprint than planned and they had to implement accommodation in the foundation, as well as the core being kinda off-centered.
@@jesustyronechrist2330 - Really? Rather than a conventional box-grid sort of layout of evenly spaced columns, the original Building 7 was 47-story trapezoidal shaped tube-in-tube steel framed office tower built on top of an existing 3 story Con Edison electrical substation building of smaller footprint which served as its partial foundation. An odd shaped building built on top of another, smaller building which it overhung. Because the Cod Ed structure was designed to have a much smaller building built over it, Building 7 used a combination of existing and new caissons to carry the load. The 5th floor functioned as a structural diaphragm, providing lateral stability and distribution of loads between the new and old caissons. Transfer trusses were used on the 5-7th floors to redistribute load to the foundation. In other words, several floors were devoted to moving the gravity loads around. Thus Building 7 had unusual attributes including transfer beams and trusses and other load transfer techniques that allowed the building to be cantilevered out over the smaller perimeter of the Con Ed foundation. These attributes affected the qualitative and quantitative structural redundancy in the building. Specifically, unlike say a traditional grid frame structure, large visible portions of Building 7 depended on relatively isolated structural elements and when those elements were compromised, it affected a disproportionately greater fraction of the structure.
Have you never looked at the floor diagram?
Simple once a major building collapses like the world trade centers did,the floors above have no foundation to stay intact
Fire will not melt steel and the simulation is based on research after the collapse. A controlled demolition is the only way to get a building to fall in it's own footprint.
What is shown here is mere conjecture. The "simulation", if it can even be called that, does not even resemble the actual footage of the collapse. So you're going to tell me that every single bolted or welded joint in the structural steel let go without any resistance like the animation? Moreover, in the actual collapse, building 7 appears to sink down as one unit. There's no pancaking, twisting, or buckling that is perceptible. It is as though the entire structure just dropped into a hole.
Pancaking? Were you paying ANY attention at all
@MFitz12 pancake...what about the the whole heavy core in center
That would be still there... building n 7... Dropped all at once
It's the only conventional building
To fall at same way....makes question uh. What was that...
But the problem with this simulation is that the building did not colapse like that
Sure it did. Collapse starts in the NE corner, with visible deformations and a vertical line of window breakage along the Column 79 line and a kink in the rooftop East Mechanical Penthouse roof. Collapse then progresses to columns 80 and 81 resulting in the EMP falling into the building. From there collapse progresses from east to west through the central core until the central core is gone, leaving just a hollow, empty shell still standing. Finally that empty shell does the only thing it can do and drops. That it twists a bit more in the Kostack model is of no significance.
There is only one problem when I compared this cartoon alongside the actual video it didn't match by a long shot.
Which part? Collapse initiation phase? The transition phase from initiation to progression phase? The progression of the collapse from east to west through the core? Or just the last and least important bit, the drop of the exterior moment frame - just an empty shell by that point that was just going to do whatever it was going to do?
Oh I didn't realize you had xray vision and could see what the inside of the building was doing in the 9/11 footage... The way the shell collapses is completely irrelevant after the interior was gone... The wind could have blown that over... Besides this is just a simulation where data is input into a computer, and a model is shown for visualization. If building 7 were to fall 20 different times it would have fallen 20 different ways.

This doesn’t look like the same collapse. The outside of the building pretty much fell straight down and didn’t tilt to the side.
Sure, but all of the truly interesting stuff happened on the inside. What happened to the exterior shell late in the collapse is of little consequence.

These guys have been studying this for years. They have been trying to model how the building could have collapsed. The most likely outcome so far is it could not have just collapsed by fire. I think you underestimate just how strong a steal frame building is and the huge forces it would take to make it drop (free fall) like it did). That goes for the twins also.

The NIST model literally matches up perfectly. Argument invalid, conspiracy retard.
it does it shows you what happens when you cause failure at those joint does the structure collapse? YES so yes that's how it happened. They just have to show you where the damage was then add that damage to the simulation if the building comes down in the simulation proves the collapse happened because of the damage to those joints.

@@genericdad6521 it was a domino effect one thing broke then it it multiple things to break then they caused more and more damage and etc until it spread through the whole building. I like this better than nist. Also, the whole building didn’t just collapse at once like the Alaska simulation. The roof started caving in in the original video you can see parts of the roof just vanish falling down then the exterior collapses.
by flying a plane into a building next to it .. yes
Just clam up dude you are embarrassing🙄
Although this seems to show ways in which WT7 could fail catastrophically, it does not show a view which exemplifies the the way it fell so evenly from both sides. Each view shows the inside failing with the outer walls falling together as a unit.
Exactly it was collapsing in a uniform fashion intil the top half of the tower hit the ground which naturally, since there was more damage on one side it fell to the side of least resistance.
It didnt. 1/3 of the building was gone, then it collapsed from a central point outward. You wanted it to be a conspiracy. Then insides fell, then the walls fell in. Just like any structure that load bearing elements have given way.
@@bartacomuskidd775 I'm not sure why you think I want a conspiracy, I'm just saying that the simulation doesn't really look like videos of the building falling down. Personally, I don't feel there is a government conspiracy but I do think that a lot of the way the ownership of the whole complex dealt with the situation as it happened and in the days following the event seem pretty shady.
@@bartacomuskidd775 "just like any structure" pffft. This is the ONLY steel high rise in history to ever fall from fire alone. It fell at free fall speed. Only a demolition can do that
For it to fall the way it did all the perimeter columns I believe 58 in total would have to collapse within a fraction of a second to produce the collapse we saw. I'm sorry but fire doesn't do that..
Pffffff fffftttttt!!! .... can you explain how the bbc said it had collapsed 30 minutes before it did on live air and then cut the live feed when they realised the building was still in the background....
It was 20 minutes and they were wrong. Add that to about a thousand other news reports that day which proved to be inaccurate. And no, they did not "cut the live feed when they realised the building was still in the background."

Wrong watch this video please it didn’t fall down at once. Look closely at the roof. And then count how many seconds it takes for the exterior to collapse after the section of the roof goes and compare it to here
@KSI ♪ . That video isn’t the “full” video This video shows what I’m taking about. czcams.com/video/e32QMAwYXmE/video.html and what I mean by that is that a large structure on the roof collapses into the roof. This could only happen if there was nothing below to support it. So why did your video skip the penthouse falling through the roof? Which happened 6 seconds before the exoskeleton finally collapsed. why didn’t include evidence that supports that the collapse initiation started before the exterior collapses? Also to start a good investigation that will get you somewhere you need to follow some steps. First. You need to start at the official theory. And look for evidence that supports and doesn’t supports it. Then you look at theories that say different things and look if there’s evidence with real facts. And the two most important things you need to remember is not to read something because it says what you want to hear. You need to read everything unbiased. And the other most important part is recognizing Occam’s razor which means the simplest solution is most likely correct. Not every time. But usually. Also my reply earlier was kinda rude. If you don’t start at the same facts as everyone else you won’t even get anywhere. That’s how you investigate something
Also the video you posted never showed the other side of the building.
@@jonahmoran3751 the "official story" doesnt know what to do about building 7. it is a total anomaly.
University of Alaska, Dep of Engineering, prof Hulsey has spent years making a digital model that will only collapse with explosives. He has published his model- NIST would never publish their model and yet they could not even make a fake simulation that resembled what we see: A building going straight down.
Correction: One obscure professor and (for a short time) a couple of grad students did a fairly low-rent and quite limited analysis of the collapse of Building 7. Nowhere in the final report this project produced does it say anything about explosives, let alone that only explosives could have caused the collapse. Hulsey merely admitted that he could not - after studying just one limited scenario - make the building collapse from fire (therefore it could not have collapsed from fire). That alone should tell you how much stock to put in the Hulsey report.
At least 4 other engineering studies have been done of the collapse of Building 7, all done by teams of far more experienced and qualified individuals working with much greater resources. All of those concluded the collapse was due to fire.
Yet another drive by truthing. Always a successful tactic.
@@MFitz12 Listen clown, the building can't fall at free fall acceleration unless the steel is taken out, *PERIOD*. I don't give a rodent's posterior about how many "far more experienced and qualified individuals" have studied it if they contradict that basic fact.

Or think.
@@MFitz12 is it possible that the "experts" that are hired by the government are liars?
I thought the owner admitted they pulled the building so what's with all the simulation
Even if he would have wanted that, it is impossible to demolish a building within a day, especially a burning one.
Kostack Studio fair point
It was the fire department who said *pull it* to Silverstein, in which they meant to pull the rescue mission inside the building as they noticed the weakened structural integrity of the building.
Thanks for your biased, uninformed input you anti-semetic fucktwig.
Why do you bigoted truthtards always prove my fucking point in the first reply?
This video shows what the collapse would look like if it was initiated by the failure of column 79 and it doesn't look anything at all like the actual collapse footage which shows the building being expertly dropped into it's own basement. For WTC 7 to fall the way it did, all the columns would have to have been "taken out" at the same time, because as the footage shows, the steel structure gave NO resistance to the fall.
Building 7 did not have a basement. In fact, it was built on top of a pre-existing 3-story building - a Con-Ed electrical substation - which served as part of Building 7's foundation.
Since you got something that fundamental so completely wrong, what else did you cock up? How would you know?
Noone cares anymore. They know they can do anything. And in a few years. You will forget all about it. Now tik tok
I will go into demolition business. I never knew that to demolish a building, all you have to do is put fire in one of the floors

IT was demolition

How you know it was not a demolition is because you fucking idiots don’t realize that the people who witnessed all of this saw airplanes flying into the tower. Enough criticizing the people who are thinking the right way. Unlike you saying that basically the government secretly demolished the building.

@Christian DiPaola All owned by 0ne person and no other building collapsed, just the buildings owned by Larry
Each individual piece of the sim only becomes detached. The build of each individual piece doesn't break down further than that. My point... nothing breaks bends or shatters in this simulation it just becomes detached.
That's because it is simulating reality. Steel can't shatter in a building, it heats up and comes apart at connections.
In regards to WTC-7...it was a dead giveaway that it was a Controlled Demolition. You have to weaken the staircases and elevator shafts first which are specialized hardened structures. They blew them out therefore the WTC-7 penthouse collapsed first losing it's footing. The penthouse may not have been directly above 8 elevator shafts of WTC-7 but it was above them including staircases. Then the bowing was there...the inner structure going down just before the outer structure to contain the debris. Then outer structure was observed to collapse on all sides pretty much in unison and that's a synchronized collapse. Finally...a freefall acceleration phase confirmed. There you have it...the globally synchronized collapse! And a few columns can't initiate this event. It's done by finely timed demolition devices set throughout the building acting in milliseconds.
Here's a video that confirms almost everything you said:
czcams.com/video/gNIzC4a8rLs/video.html
Controlled demo buildings don't free fall, they collapse at near gravity 9.81m^2. Free fall is dropping.. NOT collapsing or imploding etc...
Neat simulation. You need the top to drop straight down though, not tilt to one side. It drops straight down at full ffa for about 8 stories, make it like that.
make it like that... (great scientific process)
Not one can recreate it... Only using explosives is the way... But they try and try to explain it with the same lies... I have been telling all the people that defends this ideas... Could you recreate the world trade center with wood... Use and antorch over 15000 centigrades degrees and show me twice... How it will fall 90 degrees perfect.. Not one can.... Fire doesn't produce it...

If that’s even true, that heat would not be exist for long. And all the fuel was spent right after the impact. Sustained fires from paper and office furniture can’t melt steel.
The fires in 7 weren’t even that big.
There were so many different accounts - I remember a few stories on the news stating that 7 was brought down intentionally, for safety, due to damage because some rubble from the twin towers hit it.
If the collapse/melting of 3 pillars can cause the whole building to come down like a house of cards, I am never walking in a high rise building again. Besides, your simulation confirms AE4truth's position that asymmetrical damage causes an asymmetrical fall. Have you tried running the same simulation but with a symmetrical failure on the other side? does the building collapse look more like the real thing then?
That is an incredibly ignorant statement.
They don't, we would have see it many times before if steel buildings suffered from instant collapse. Termite residue and microscopic iron balls and sulfer found all through the dust. The well connected new owner of the wtc, double insured the complex for terrorism. We all know there was prior knowledge of the comming attacks. Abestos filled only 60% occupied losing money. Lmfao!
Champlain Towers in Surfside, FL is an example of how a single failure can bring most of if not all of a building down
@@MFitz12 Kaching!!! How much you get per comment?
There was no melting of 3 pillars. This collapse theory was based on thermal expansion of one beam pushing an adjacent beam off of column 79. But absolutely, where was the Resistance from all of the adjacent structure? All of the bolted and welded connnections. plus the model did not include the sheer studs from the cross beams into the concrete flooring that also ties it all together. But you're right this theory acts literally like a house of cards.
Why didn’t they show the charges and the point of detonation?
Every charge and point of detonation from the real event are shown. All of them.
You have no brain
@@genericdad6521 Ha!
Perfect way to smoke that guy. 👌😂
In actual footage of the buildings collapse you can actually see the exterior near the roof bend into a v shape before collapsing, there's also another tape showing the back of the building collapsing, in that footage you could see the building tilt before hitting the ground.
It doesn't turn to dust.

yup
That's not how the building collapsed. They'll think people are stupid
Part of it is underestimating us intellectually, but most of it is just trying to intimidate us.
Looks like a perfect demolition!
This cartoon is not reflected the reality (
On actual field side tape that captures the collapse of building 7, looks like the top of the building collapsed straight down and all at once. It was commented later buy a structural engineering that the footage shows the building too collapsed at free fall speed, like there was no structural underneath to support it. Just like a demolition then all or most support columns are strategically blown up from bottom to the top so the gravity complete the job.
Also, this cartoon shows that all walls of the building was pushed outside on the bottom of the building and then collapsed at ground level. In reality, exterior walls on the bottom of building 7 was standing (bottoms floors), then the rest of the building was acutely collapsed inside as only interior structural was compromised.
What does a "perfect demolition" look like?
Why?
What does a building collapsing look like with no pre-planned demolition?
The Kostack model collapse mechanisms are accurate. Interior of the building fails first, then the hollow empty shell that remained on the outside dropped. Who cares how fast that hollow empty shell drops? Why does that matter? There was no support under it. The inside of the building (the support for the moment frame) was long gone. It's right there in the model.
this looks completely different from reality ...
Well yes, because this model shows everything that is out of view in the real world event - which is almost the entire collapse.

did anyone do a WTC7 simulation as per a typical controlled demolition? The 23 vids of collapse look like a controlled demolition.
Agree. Unless somethings wrong with those cameras shooting while it collapsed. The building seemed more or less "plane" as it went down, like a controlled demolition. Not like on this video.
As if all the internal structures were gone when it fell
You mean the exterior moment frame? Yes, all of the internal structures failed in sequence as shown in this model before the then hollow empty outer shell collapsed. Just like the model shows.
This is probably the most inaccurate reconstruction I’ve ever seen.. how is this still on CZcams? This looks nothing like what happened to WTC 7 at all... disliked
Not a reconstruction. It's a model designed to test mechanisms, not an artistic photo realistic rendering. Big difference.
What seems to be the problem? I find all the important bits very accurate, only the unimportant but visually more spectacular bits less so.
Bro I just think you just got your worldview rocked and you're upset about it. If you actually watch the UNEDITED version you will see the penthouse collapse.
Interior of the building is falling like it's a house of cards. That's simply not how steel frame structures react. An actual steel structure would put up much more resistance than what's shown in this video.
If you want to see an actual scientific explanation of what happened (or what didn't happen, I should say), check out the work of Professor Leroy Hulsey of the University of Alaska.
correct
It's amazing how many people think they are structural engineers because they watched a video.
Including people like you.
It's amazing how many people think you need credentials from academic institution to see that a building clearly fell straight down, just like a controlled demolition. No fancy sounding credentials are needed - only basic intellectual honesty is.
Maybe someday we'll be able to model things like this in real-time. Call me weird but I'm so fascinated by this sort of thing that I'd love to be able to set up a simulation of this sort and just watch it do its thing.
Model in real time??? Not sure what that implies. The geometry and materials have to be accurately defined for a finite element assessment to be accurate. I would not trust the comic book like analysis results of the truther 9/11 report they paid for from Fairbanks Alaska University (two of the 3 structural experts were Chinese nationals on education visas) that was peer reviewed by two guys in their mid 80s.
You'll have to wait for quantum computing. Simulating each particle in such a large scale simulation would take astronomical processing power. Classical computers cannot keep up with such a demand, it would take thousands of years. On a quantum computer it would take an hour, tops.
@@mattaddison1910 The 9/11 Truther simulations are cartoonish and some believe they prove WTC7 was brought down via controlled demolition. While I don't believe everything the government says, I think the chances that the CIA was behind 9/11 is very very unlikely. The terrorists got lucky to have that level of impact and opened the door for a lot of conspiracies like the claims pushed by the 9/11 Truthers.

Most of the fuel would flash burn collapsing twin tower walls. Not iron I beams especially with central air. The induction vents would starve the flame of air.

What does bother me is the lack of curiosity by government and media about Bldg. 7, because if it really did collapse due to fire then it needs to be studied and understood in it’s entirety, because there are thousands of similar buildings all around the world. Are they ticking time bombs? The fact that the debris was so quickly removed rather than retained and analyzed is also troubling.
3 major engineering studies, about 2 dozen articles in peer reviewed engineering journals and it has (quite wrongly) been the primary obsession of the CT crowd for 15 years.
In short, it's been done to death, quite the opposite of the lack of attention tou claim.
"Are they ticking time bombs?" High rise fires are typically fought.
It wasn't feasible to fight the fires in 7 after the towers severed the water mains, so it was left to burn. Steel structures have a fire rating for how long they can withstand being on fire, firefighters of the FDNY knew 7 was unstable and expected it to collapse.
This looks nowhere near what happened that day. A computer model is in no way going to answer the questions, on both sides of the coin. Real-world experience cant be replicated like this. All your doing is trying to find something that can match as closely as possible the collapse of the building. Clutching at whatever straws u can doesn't mean anything. Until another highrise comes down to make a comparison well then it's not possible to happen the way u say.

You might not know the meaning of words. That would be a very long way to bring yourself up to date, to the rest of the people's universal understanding of them. Assuming you went already to those years of school. (or maybe not ?)
Your collapse model no way resembles the actual footage, from any angle. Especially the colossal chunks leftover in the rubble. From every angle it's seen at, a perfectly fine building sinks into the earth and becomes so much powder and steel fragments.
Actually its almost dead on except for a few minor details.
It's amazing what the failure of one steel column can do.
Depends on the column but yes.
There are contradictory simulations that imply the column connections from 7 floors would have to be removed to have a collapse as seen on 9-11.
In fact, Professor of Civil Engineering J. Leroy Hulsey at the University of Alaska led a 4-year (2015-2019) investigation titled "A Structural Reevaluation of the Collapse of World Trade Center 7" which concluded thar "the collapse of WTC 7 was a global failure involving the near-simultaneous failure of every column in the building".
@@kodowdus his 'analysis' is deeply flawed. Don't try to cherry pick just to conform to a preconceived ideology. All of the buildings around the twin towers were badly damaged; all of the WTC buildings were destroyed with varying degrees of full collapse or structural compromise.

Close to free fall? How close? Why do we care? How does how fast something falls inform you as to what started it falling?
@@MFitz12 cauz its physics. Physics are just basic of every fuckin machine you get served with.
@@Viggebob This! The rate of fall is critical to identifying the proper failure mode, as well as symmetry and failure sequence.
A building with structure under it cannot accelerate at free fall. A building with floor connections failing would pull the exterior face inward and damage it. You would see glass popping out in synchronicity with the floor failures.
The total collapse was much longer than a free fall. At one point the perimeter wall (as observed from a distance on a VHS recording) descends at an acceleration around (and exceeding!) g (9.82 m/s) - that's it.

Why? That isn't what happened. The bottom 7 floors aren't even the same building.

It's easy to predict what would happen: The building would fall as a whole intact structure until it hits the ground, however, this also means that the penthouse wouldn't collapse first anymore.

@@ThaJoshynator after watching all the simulations, including NIST's, it's painfully obvious that structural failure is a joke. University of Alaska Fairbanks recently did a report on this and found the only way to model the traits of the collapse (symmetric free fall for 2.8s), requires the near instantaneous failure of every support column of at least 8 floors
Is quite curious that the three buildings fall down in a similar way, but for different reasons...
By different way you of course mean structural damage and fire, they also had the same basic open floor truss system.
The Twin Towers collapses are similar although there are significant differences. But of course, they were identical designs and suffered similar (but not identical) damage. Building 7's collapse could not have been more different from the Twin Towers.
@@MFitz12 Yes it could've. It fell right into it's footprints like the towers did. No other skyscraper in history has done that and collapsed in a similar fashion from a fire.

@@fightzombie229 buildings tend to collapse like that because the force of gravity is greater than the rotational force that would make a building fall sideways.

So unless I have missed something here, Im interested in what ssimulated action you used to initiate/catalyse the collapse? Did you remove column 79? Buckle it, or slide it away from its initial connection? or something else?
Also Im interested if you have seen the UAF report on WTC7 2017?
Horizontal and vertical connections around columns 79 to 81 were weakened in this simulation to enforce the collapse.
I'm aware of the UAF report and while I acknowledge their efforts to do further research on the matter, I don't think they can reach their target to ultimately prove that fire wasn't the cause. Maybe NIST didn't determine the correct point of initial failure but this doesn't rule out fire. Don't have to high hopes for revolutionary new insights from their work.
"Horizontal and vertical connections around columns 79 to 81 were weakened in this simulation to enforce the collapse" - Ok I appreciate your reply, but that to me is consigned to the values and tolerances of your software, which 'could' be way off reality and 'could' essentially mean anything.
I have used 3DS Max since 2003 so have some insight into these processes!
"I'm aware of the UAF report " - Ok but you havent taken the time to watch the presentation, and yet you say "Don't have to high hopes for revolutionary new insights" Hmm why would you dismiss them so quickly? Do you think they would have a motive to lie?
"Maybe NIST didn't determine the correct point of initial failure" The NIST model is an absolute joke and barely resembles reality, and they said fire alone was the cause!! What do you think?
Obviously no-one can recreate the event to 100% accuracy, but curious to know if you think your model would be more technically accurate that the UAF one? because your sim although very impressive still does not resemble how the actual footage shows, the corners and the roofline are a big problem here!!! and im no technical slouch, I just cannot find any other way of explaining this other than CD.

Godzilla did not stomp on it or melt it with his atomic breath.
One critical core column is failed. That's it. what caused it to fail is not important, only that it failed. From that initial failure there is an inevitable progression to total collapse REGARDLESS OF WHAT CAUSED THE INITIAL FAILURE. From the point where collapse is initiated all the way through the progression stage the collapse is near-as-makes-no-difference a dead ringer for the real world event. The same progression of failures occur in both.
The ramifications of this should not need to be explained but I suspect I will need to anyway.
