It's calculated for per metre length if you want you can multiply it with 3m but then you put b=3m in the equation M=0.138fckbd^2 ... As he calculated the moment per m length he put the value of b =1m . Either way the value of d will be the same i.e. 369.84mm
Nahi, assume 10% hi kiya jta hai, agar footing ka weight baad me nikal k aaye 20% load k approx tab fir design change kiya jata hai, orherwise assume 10% hi karna hai.
Video is very helpful sir..thanks
Good morning sir 👏👏
Moment is mistake i guess. Its should be multipled by width again
Please check the calculation for moment criterion, the moment calculation in both direction is wrong to find the workable depth
wl ^2 / , where w is load per metre, its unit is kN/m
Thank u so much , Sir 🙌🏻
Sir previous ka year ka bhi questions karwa dijiye please sir 2019 aur 2020 dono ka
Sir aaj kal class stop kuuu hai????
Thora Break liye hain, Fir start kar denge 1 week me.
One way shear me tawc ke value 0.25root fck kr sakte h
Nahi, 0.25 root fck permissible Punching Stress ka value hota hai, nahi le skte hain
Sir wsm method se beam column slab footing lintel ki design upsssc exam mein aati hai sir ye bhi padha dijiye
Competitve exams ki tayyari karaenge aage, Usme WSM and LSM dono hi methods bataenge
@@dAdSir sir kb se usko start karenge
Aage inform kar denge, uske liye proper planning karna parega. Hopefully SSC JE ka form aane k baad hi start karenge
@@dAdSir okk sir lekin upsssc je ke liye hi padha dijiye uska exam Oct mei। Hai
Pressure *area =force hua na sir aapne jo Wu (kn/M2)*(L-a)square/2

Self wt 20 % bhi assume kr sakte hai footing ke liye .....
