instead of just mentioning clause number, you may show it which will make easy to understand for everyone
Q bhai in b मेहनत ni करनी kya की khud check krlo.. Hdd h sara khana हाथ m chaiye... कोड़ी हो क्या 🤣🤣🤣
Thank u sir, explanation is best with page no. And clauses..
rethink about the minimum and maximum Ast, what you have written is meant for beam and not for slab...check clause 26.5.2
Bro,the minimum steel in slab for Tor steel is 0.12% of Ag and for for mild steel is 0.15% of Ag. The formula which you have stated in the video is for beams.
sr aapke nmbr give me rcc.... information ke liye
sir, how did you take modification factor as 1.5 without considering Pt and Fy ?
Brother fy is given you mean fs
Because MF depends on both Fs and %Pt
U can easily calculate from the is code
Ok
See here to know
280/3stress in steel
Thank you so much sir
perfect explanation! thanks a lot!!
1m should be multiplied not divide in load calculation step
By your video, i got 93 number on RCC ,without using any code.
My teacher also shocked , because they was gave me 21/50 number.
❤
How 38 years ago you commented??
But you will have failed in english surely
So happy to hear that ❤️
Explain briefly about arrangement of bars
Like distribution bars and cranked bars
7:14 correction
For udl multiplying by 1 m
you have done a blunder, for one way slab IS code has given bending moment coefficients. You cannot simply use wl^2/8 ,
That's for continuous beam I think and he assumed simply supported slab
@@see-willconcepts9776 yes you are right , he assumed as simply supported slab
In deflection check of both one-way and two-way slab, why percentage of steel is taken only for main reinforcement by ignoring addition of steel percentage of distribution? Reference [IS:456 2000, or any valid book following the IS Codes]
minimum reinforcement in case of slabs is taken as 0.12 percent of total cross sectional area when HYSD bars are used. The formula that you have used to calculate minimum area is used in case of beaams.
Good and Informative
This Ast min is used for beams not for one way slab
Super explanation Bro
Nice voice Sir ji
Isi se related column design karna tha bhai next video me
Sir we are provided cranked bars in shorter span
Sir thank you for your amazing Explanation of detail design for easy Understanding . I would like to know how to calculate No of Bars in Steel Calculation after computing Ast value ?
Decide the diameter of bar first. Then in case if beam the no.of bars = Ast/ area of one bar. In case of slabs we calculate spacing of bars in 1m width of slab. Then in slabs spacing = ( area of one bar/ Ast ) X 1000 hope u understand
Check for minimum and maximum area of steel are for beam
Yes for tension steel check need to be done to ensure
Minimum steel provided against cracking and maximum steel to prevent from being over reinforced
Why minimum steel is necessary?

How to measure the slab into square feet,if it is round ....like a sump(under ground water sumps)
Sir if Ly/Lx = 2 hai toh one way slab h ya two way slab????
Two way slab
Check for depth m= 0.36 (how please explain me)
Bhai ye Ast ke formula ka reference kaha hoga IS code mein. Ek pt ka bhi formula hota hai. Uska reference bhi kha milega IS code mein. Ast konse design ke liye use hoga and pt (percentage of steel) formula konse design ke liye use hoga. Kindly clarify this doubt.
Ap dono way se design kar sakte ho..pt se bhi aur ast se bhi..
Ast wala formula derived formula hai nai milega is code me.
@@EverythingCivil If in case, apko mile ye formula ka derivation. So, kindly share it. Us se reference dena easy ho jayega.
Yes ok . U r right
Why you taken shorter span as span length in first step
Sir,, the formula of Ast used in the above problem take from which IS code???
Is 456:2000
design load is not calculated , to calculate design load 1.5 *total load
Right sir
Span /25 for slab case if i am right 25-30
For simply support beam is 20
Yes sir
How to calculate check for depth
Nice bhi
Why we take half od diameter in calculations of D
Because we consider tensile force to be acting in the steel bar at its centre therefore D-cover-d/2
Distribution r/f is not calculated
what if the ratio of the slab is equal to two what is it one way or two way slab?
It will be two way slab.
Where is distribution steel calculation ?
last wala minimum aur max. wala critetria to beam ka hai....galat bata rahe ho...
0.85bd/fy was for beam no?
for slab its 0.12%
Bro why u take FF is 1.5
Floor finish - including weight of bedding mortar and tiles or any other coatings. You can modify it according to ur requirement
Sir her it is one way slabe
Yes
Very interesting and well presented. But I just cant seem to calculate "Check for Depth" using your formula.
Can you pls explain step by step your calculation. Maybe I miss something but I get totally different values.
Appreciate your input.
Mu = 0.36 x (Fck) x (xumax) x b (d - 0.42xumax) In this equation put Mu , the moment you calculated and d will be unknown.
Thank you, do you have email?

Wrong calculation of load calculation
Thanks sir
Thanks for watching
why not considering negative and positive moments as per table 12?
This problem is based on design of simply supported one way slab.
The coeffecients given in table 12 are for calculating (+) (-) moments in continuous slabs. There are no negative moments in simply supported slabs.
Please watch this video to know the difference between simply supported and continuous slabs : czcams.com/video/Y9v2_slISx4/video.html
Everything Civil thankyou
You're welcome.
Sir ast min m distribution steel ka concept ky kiye
Plz correct kriye
Can i know from where did you get that 0.48d for fe 415 Steel in code book?
You can find it on Page no.70 of the codebook
Please give me link of all slab videos
Sir is there any difference btw one way slab and one way continuous slab ?
If yes then design procedure of both is different ??
Yes they both are totally different. I have made a video on design of one way continuous slabs
@@EverythingCivilsir You have taken in depth of slab basic value as 20 which is of simply supported but slab is one way continuous slab them value should be 26.
10:35 i don't understand why you used 125 as effective depth instead of 78.
It's for safe design. If you take the minimum depth as your effective depth you slab will fail in deflection.
yeah but 125 is the assumed depth and 78 is what we calculated.so what's the point of calculating if it is not used.
is it like .. we have to use that one which has a bigger value.. be it assumed or calculated.? pls explain.
I think we should use 78 and not 125 to get Ast.cuz that's what u did in two way slab.
Thanks for explaining
Thankyou so much sir
It very helpful video
can we decrease the value of modification factor so that our depth will be large? as you have taken 1.5 instead of 1.7 as a result every where the safety conditions are satisfied..
Not economical
sir if slab is 8feet*17feet where as supports are at 8feet span so can it be designed as one way with main rod at longer span
sir how to decide which diameter of steel bar to be taken?
Depends upon your area of steel.
For eg for a beam you need minimum two bars so choose a dia so that two bars will give u the ASt
Generally u will se 12mm to 20mm bars in beams
For slabs higher the dia higher the spacing and lower the dia lower the spacing. Generally u will only se 8mm and 10mm dia in slabs.
What to do if spacing doesn't satisfy the conditions?
Please do two way slab also. With four storey building
Sir what is the formulae to check depth in case of doubly reinforced beam,
Please reply sir
Watch here to know
What if i have to design one-way slabs and two-way slabs for the same building, how do i determine the minimum depth of the slab?
See here to know
Good evening sir
I am impressed one way continuous slab..
Sir ek video one way and two way
Continuous span slab ka jaroor banay.
Thanks siir
Yes next video is on two continuous slabs
Way*
If I provide 100mm of slab then it is correct or not
Why we r consider as shorter span value...?
How to get Check for depth equation and calculation of steel?
By taking moment of Compressive force about the neutral axis.
Claws kon btaye ga?
Can you please make video on design of slabs columns and beams by using ACI codes
I haven't studied that code. I make most of my videos based on the Indian Standard.
Sir why i am not taking factor load by multiplying 1.5 ?
He multipied it later while calculating momemt. You also calculate factored load before by multiplying the service load by 1.5
How to check the value obtained from development length
Why you take formula for effective depth in multiples with MF but not mentioned in IS code .
MAKE A COMPLETE VIDEO FOR LOAD CALCULATIONS
sure, can u tell more on what you want a video?
FOR DESIGN A BUILDING, FIRST WE NEED TO CALCULATE LOAD, PLEASE DISCUSS THAT IN DETAIL AND PLS ANOTHER VIDEO ON HOW TO DO COLUMN LAYOUT WORKING DRAWING
nice video sir. please upload more
Sir I am waiting for the next steps in one way slab
What's your name ?
9:25 From where in the code have you taken the formula from
its not directly in the code. but if you see pg no 69 fig 22 of the code. there you have to calculate the moment along compression side for that the force given is 0.36.fck.xu.b and the lever arm is (d-0.42xu) therefore Mu=forceXlever arm
Everything thank you. I checked it there and found it .
One more question about the formula used at 10:16 . Is it also given in is code ?
NO it is not given in the code. It has been derived by equating Cu and Tu
Ok thanks for the help
sir area req 402.16 how to come
