Got a degree in transportation engineering, although it wasn't the best learning experience. Ended up getting a 1-year contract work on a local railway project, but it was strongly-tied to civil engineering (particularly the building of stations, railroads, drainages etc.). Now my contract is over, and I wanna try using this blank period to relearn more about civil engineering principles and mindsets in hopes I can land another job opportunity with a fresh mind. This video was very inspiring, thank you!
Great video. Professors will have students believe that when they start working, they will be calculating the most advanced calculus by hand with no calculator all day long
Your videos helped me a lot. I'm about to graduate.
Back when calculators and computers were not widely available, engineers did calculus, differential equations, etc., by pen and pad. My teacher for non-rigid body mechanics from two decades ago was an old engineer who very good at doing engineering math "manually".

Great video. I am a structural engineer with 27 years experience. How you explain software and how it needs to be back checked is right on. Great job! I try to tell my younger engineers exactly what you said. I enjoy your channel. Keep up the great work!

If you actually like math and still want to become a structural engineer, I would suggest going into water resources and do work on dams and hydroelectric plants. The reason being is that all dams are regulated by FERC (Federal Energy Regulatory Comittee) and they require all designs to be backchecked and approved by them and they don't have any finite element software. Therefore, nearly all calcs have to be done by hand or using software like excel and maybe Visual Analysis. Thats how I spent my first 3 years. Was very interesting work.
Thanks for sharing, that's interesting!
Yea but surely finite element software will eventually be released for dams in the near future
Can someone work at a Civil Engineering firm with a undergraduate or graduate degree in Applied math or English?
Hey man, thanks for the video. Really enjoy watching your videos and the content you create. Keep it up!
Vector statics is so fancy…I use scalar statics in my everyday job😅
Which direction is that load in?
4....
High magnitude joke
@@martinvanburensleftsidebur5329 as long as you have the magnitude, you don't need a direction...
a solid understanding of statics...shear and moment diagrams, spatial reasoning, guestimation, being computer savvy. this is what will make you valuable in the industry

Maths are great. Interesting, useful, fun, and frustrating at the same time. They can be very complicated at times, but after 500 problems they are not complicated anymore.
Thanks for sharing this!
hi, I'm an Italian freelance structural engineer, in my daily practice I use a lot of linear algebra and systems of equations. As for the statistics, it is essential to decide the various tests to be performed on existing materials and buildings, and how to interpret the results (we are in Italy, most of the work is on historic buildings).
Calculus is essential, to validate the calculations that return the software, as well as to program the software.
As for the FEM, it is the basis of the routine of most structural engineers. Unfortunately, many colleagues blindly trust the programs (often too user friendly) and are not aware of what they are doing, unable to dominate the amount of numbers and data. Again, here too, manual validation of the software outputs is needed for every project, whether structural or geotechnical.
Obviously, software is used in the everyday profession, but it is necessary to know the behavior of the structures, and evaluate the goodness of the results.
PS "stop asking which software should I use" THANK YOU, HALELUJA. finally someone who says it. each project is your responsibility as an engineer, not that of the program.
we are engineers, not clicker monkeys who input data
Agree with everthing you said. Greetings from Brazil.
@JoãoM in Italy and in Qatar or Dubai where i operate i use fem for the 99.5% of the work, for the complex but Also for the simple case. Only for the extremly simple case i don't use fem, but the big quantity of load combination.....it's so mutch faster using fem
@Paolo Scarparo, hello sir. If you don't mind could I ask a question about what kind of tasks you have to deal with everyday as a freelance structural engineer? I'm very curious about your job specifically in freelance business. Thanks you so much.
Grandeee bellissimo Lavoro ti invidio

Thank you! Another thank you for your inspiring video Mat!

Can't wait to learn more from your videos
Very informative video. You should do more like this. More power bro. 👍
I've been working as a structural engineer in Russia for 12 years and now I'm doing Master's in Germany. Maan I struggle with that tensor calculus and dream about the day I won't ever touch it again 😂

Ensuring dimension (units) are right and keeping a grip on proportion or some other frame of reference. Always understanding the numbers, never letting them become meaningless numbers plugged into a formula without understanding.
Great explanation! Great content overall
My chemistry teacher in hs who is a chemical engineer would tell us that engineers don't need to memorize every formula or do calculations all day long cause that's what calculators do but we need to know what we're going to do so then we can tell the calculator to do the rest.
100% agree on the point you are making about the most valuable skill. Anyone can model a building with the easy approach FEM software available nowadays but not everyone can do the interpretation of the results. I do a lot of structural analysis of mixed timber/ steel and concrete constructions and knowing the (in this case) anisotropic and inhomogenous behaviour of timber for example is absolutely key. Sometimes I tutor students at my old university and they often ask me how I got as knowledgable about the and I often told them: Learn the fundamentals of mechanics, structural analysis and really try to understand them! Question why formulas are designed in a certain way, try to really grasp what e.g. shear stress is, understand why open and closed cross sections behave differently when exposed to torsion etc etc. Always question what you are presented with. Love your videos btw! Not a lot of earth quake design in Germany so it's good insights :)
Great Points.
I’ve been waiting for a video like for a longggggg time
Vector statics is the basic you use as a daily basis. Agreed. The structure or the mechanical system is supposed to survive or function well in a random environments. Knowing more math, it is helpful to understand the ‘design codes’ well and the computation behind it. So you get to know how to adjust parameters in FEM software. Especially, the wind load and seismic load are the two , which needs more math to understand as well as how to analyze , interacting them with structure itself in design codes.

Thanks for sharing your knowledge and experience with us! I'm a brazilian civil engineer and I really like about your videos.

Very on-point video, been working as a structural engineers for almost 2 years now and it is totally different from what my university has been teaching. In my university, the parameters and assumptions are all given and we focus so much on calculating using equations given in various code of practice (which is the easiest part to be honest), but missed out the point on what is the most important as a structural engineers! Its not only about calculation, its more on the how and what are the assumptions made and understanding the behavior of the structural elements. Got a culture shock when came out to work even I have studied structural engineering 😂
useless if your fees are so less. Compare with lawyers.
To be honest... In this online school setup here in the philippines, I can't even understand nor learn something from my Statics of Rigid Bodies subject because I feel i'm just passing some school requirements and then just move on.... I really want to learn that subject cause im planning to take structural civil engineering... I just feel bad for myself being like this.... Now I feel pressured after watching this video :(
Hello po! How's your civil engineering journey?
Great video
OMG, we were just taught today the dynamics problem you showed in the video
Great video sir. I am an Indian structural engineering student and follow your videos and idea being structural engineering
All the best!
THANK YOU.
Thank you for the information, I've spent the last 13 years working for a manufacturing supplier dealing with civil infrastructure, major and minor works, level crossing removals, highways etc, you name it, probably done it. I've recently quit and am looking to put something towards my knowledge, experience and skills that I've gained over the years. I've been dealing with designers, engineers and much more on these projects over the years and I feel I really want to be able to do more. Thinking about going for an associate degree in civil engineering, I'm not sure if this is the right call and am still trying to figure out what to do, I hope it's the right choice if I go for it... Any tips would be wonderful, and I'll be ever grateful!
Thanks a lot
My statics and mechanics professor is horrible I hope to get through this class.
hello sir im a young structural engineering student can you make a video on how different structural members behave on loads .just a watered down version coz all i know is maths not the actual theory behind it.
We are both using ti-36x pro calculator. I'm a 3rd yr civil engineering student. I really want to be a structure engineer, thank for this vid I've got an idea on what ur doin, im afraid coz Im just an average student. 😁😅
Hey Mat! Great video. I’m a college studying studying civil engineering at Georgia Tech, and I’m interested in both construction and structural engineering. That means I have to be a little more selective when choosing my electives. Can you make a video on what electives you would recommend that I prioritize for structural engineering? (Geomatics, steel design, concrete design, timber design, etc.) thanks!
@Ben Yehudah I’d love to go into the vertical construction sector. Either designing buildings or managing the projects- I haven’t decided yet.
What gpa did you have to get into tech? I wanna get in too
@@brownie4032 I had a 4.0, but I wouldn’t stress if you don’t have that. Involvement helps you stand out in your application. I was the Vice President of a cultural club, volunteered as a mentor in a robotics competition, and was involved in activist projects in my community. Good luck on your application!
i learn a bunch of stuff on how to design columns of steel or concrete, how to design slabs and footings, designin of building structure based on the country standards....but as a student how do i remember everything.....you mentioned some stuff that i learned also
In the design industry, you don't have to remember all the formulas and it's not expected in the licensing exams either. You just have to know how to find and use the equations in the code books, and then you should be fine.
@@MatPicardal when you first get into the industry, were u job ready or was their someone to help? honestly, i feel like as soon as a year of my degree ends, i forget like 80% of what i learned. Also, what was the first work you did? As a student looking for internships, what should i keep an eye for? thank you
Enjoyed
I kept asking myself why the math and hand calculations were still being taught if they will not be used anyway. You addressed my curiosity. Very useful if you wish to pursue research. And to a certain degree, I reckon it gives you a better appreciation of the results if you are able to relate the numbers to the expected behavior.
Back when calculators and computers were not widely available, engineers did calculus, differential equations, etc., by pen and pad. My teacher for non-rigid body mechanics from two decades ago was an old engineer who very good at doing engineering math "manually".
He actually understood what the math represented in real life instead of just memorizing the formulas and techniques to solve them.
The long span beam example looks wrong. Deep I section, narrow flanges. supported at the ends by web cleats, only two lateral restraints in the span. My guess is that lateral-torsional buckling governs the permissible stress.
Another point - the deflection doesn't increase exponentially with the span; it's a power law.
Hi Mat, I'm a 38year old carpenter apprentice.
When working in the carpentry jobs on site, I always think why the structure is designed, such as: if the post depth is shorted how will it be a concern to a house, why an installation using 3 screws not 4 screws, etc. That's make me considering to study structural engineering for interest and maybe even helping me in design a house structure in future.
However, I'm already 38, I need to work for my bill, I dont' have so much money and time to study a full-time degree. Could you give me some suggestions? Any website or short course, etc. suitable to me to have a beginner start to learn about structural engineering? I still don't know if I really want to study a bachelor or master of it.
I performed bad in pure mathematics in high school, these two days I tried to have a quick look about the maths I learnt in high school, I have some confidence I can do better now.
At this moment, I don't really imagine I will be a certified structural engineer to build a bridge or skyscraper, but I actually want to learn the art of how structures are designed and calculated?
Thanks.
Hey Mat! Great Video. I heard you throwing some shade at technicians at around 8:23 lol i get what you mean though. I do want to ask you though; In the United States, where do technologists fit in within your field. I'm from south africa and here you can get what is known as a BTech Eng degree in engineering after completing a 2 year postgraduate course, after you've completed a 3 year course to become a technician. That's 3 years = technician + another 2 years = Engineering Technologist.
Basically what this qualification does here is it let's you operate independently, you can register with ECSA (Engineering Council of South Africa) after 3 to 5 years experience as a professional civil engineering technologist (which I'm going to do soon) and this enables you to basically sign off on the same projects that registered engineers can sign off on.
Im just curious about the role technologists play in the united states.
Thank you I’m really looking into getting into civil engineering I’ve been in the building businesses my whole life and what to move up I know I’m really late getting into school but what about online classes
You should play the Infra sim game is like civil engineering game
Great video sir. Sir I'm an upcoming structural engineering student sir from the Philippines. Sir Do a structural engineering majors do some architectural plans too or can be a contractor too sir or things inline in the construction engineering sir.? Thank you sir
Can somebody explain what he's doing at 3:06 ?
I completed bachelors in Civil engineering and I'm gonna study masters in the USA, but I don't have any software experience like ETABS and others because I just graduated and i don't have work experience I want to study masters in structural engineering, so are there some software class along with other course or how do I get software class during master study. thank you
❤❤❤😋😋 i love this channel ..one day i wanna be a cool and perfect engineer like u.......i really mean that....
Great video, which book do you recommend for learn FINITE ELEMENTS METHOD?
Don't have one off the top of my head. The one I used to have wasn't great and mostly learned from my professor on that class.
5:37 🎯💯
I'm a welder and although it will not be my profession, I understand the value and importance of everyone on the job understanding some aspects of structural engineering specifically the behaviour of materials under stress strain and under the influence of various elemental factors and disasters. I plan on learning the math and self learning about structural engineering because it is so god damn cool.
If you had to recommend some user friendly books on structural engineering what would you recommend?
The books that are widely used in the United States are by Hibbeler. The start is Engineering Mechanics: Statics, and the subject after is Mechanics of Materials. You definitely need a firm grasp on algebra and basic geometry/trig for most of statics and a general understanding of integral calculus (which is mostly used for curved shapes and explaining the area under a line). Jeff Hanson on youtube covers these topics well.
simplified steel design is good for you but you need an understanding about mechanics and strength of materials

So anyway. What software should we learn?
I like Linear Algebra and Vector Calculus
In third semester of uni, currently wondering why im breaking my head and putting massive amount of time into physics 2 (electricity & magnetism). Im doing well in the course, but it feels like a total waste of time
I do believe all physics help you develop a good critical thinking
Yeah, some classes you just have to pass and hope that they help you in other classes. Focus on your end goals and those classes are just an obstacle you'll get over.
@@MatPicardal Yes, Thats very true. I can't wait to take statics next semester
In which chapter basic knowledge maths we should know before joining civil engineering
Hi!
I'm a recent high school grad and I took physics, chemistry an biology as core subjects with general studies and basic applied mathematics (BAM) as extra subjects. I got an A in physics, B in chemistry and C in biology as well as a B in basic applied mathematics (BAM). I'm looking forward to civil engineering but I don't know of my math is eligible for taking it or not (bevause it's not advanced mathematics, tho we touches on the basics of calculus ir differenciation and intergration in BAM).
I'm interested in structural or transportational engineering within civil. Can anyone help tell me if I can enter into it or not based on my maths and if I would be capable of handling the maths there. Thanks!
Good day sir..i am from india..please suggest some of the books on structural engineering..if possible links also to download those..
Nice channel
It always involves in any eng field some problems are just purely math related.
you recommended a software for making design calculations look professional in a previous video but i cant find it now, what was free software???
also does it do euro code equations or just the American standard?
For nice hand calc software, it was MathCad. I've heard of SMath as well. Here was the video czcams.com/video/ArKQMvnZLs4/video.html
Hello Mat 👋
How many hours a day did you spend studying while you were at University?
Learn Core Civil Engineering Problems Here🇺🇸🇺🇸🇺🇸
Folks say Math is a building block. I took assessment test at community college and started at elementary algebra and went through Diffy Qs. Truthfully I only felt I had to really know previous math courses in Diffy Qs.
True, unless you go into research where they do a lot of derivations and more math
In my nearly 50 year career in structural engineering, I never used more math than I learned in pre-calculus. I took Calc 1 & 2 and never used it at all.
It surpricing me you didn't use that much calculus for 50 years of career.
Z2
Agreed

The Math also used in Computer Science bro
The most basic math is Interpolation. Correct me if i am wrong.
As a civil engineering student is it better to take notes digitally or with paper and pen?
I consider myself a digital enthousiast... professional drawings, calculations and reports are made with a computer... My notes are written on paper by fountain pen or pencil all day long. Being able to communicate your ideas with paper and pen is an important skill for a civil engineer - I am still grateful for the teacher that 'hammered' that in... lots of old school note to occasionally have a look at and an important engineering skill to use every day.
both
Hi, thanks for the video. I'm structural engineer from Checheniya (seismic region). How do you calculate the seismic overturning probability of the building? I really appreciate any information or material you may provide.
Tough to answer over comments. You'd probably want to get a seismic book for examples. Essentially, you calculate the overturning moment (shear x height) and compare it to the resisting moment (usually building weight).
@@MatPicardal Thanks for the answer. in the case you mentioned you got moments acting about different points, which is not quite correct. If you have any books, articles on this topic I'd be grateful if you share.
Math is just a tool that engineers use. Once you get into the higher level classes you'll realize that you only use basic arithmetic and trigonometry.
Are you a Filipino?
Yes!
Luckily I did physics instead of engineering. Having had the chance to do both scientific and engineering jobs, I can tell you engineering jobs require a very small or no amount of math at all. The scientific jobs were way more interesting.
We want to be trained in Earth quake structural design
I'll share this video to all my neighbours who complain about my 1800w sound system. 😒😄
Message lang sa videos ko palakihin natin mga channel natin...
Now you are scaring me😭😭😭 trigonometry yes, others not so well
I failed multiple math classes before the advance topics. you can learn if you learn from many resources like online and lots of effort
😳
All this shit looks like equations from another planet.
Yep, engineers must think ahead of the norm otherwise we just act like trained robots doing exactly what our forefathers did 100yrs ago without any real breakthrough in design reliability and costs.
wtf bruhhhhhh🤣🤣🤣🤣🤣🤣 shit look hard but got try
