Detailed steps to design One Way Slab has been explained clearly, all the checks ie check for deflection, check for development length, check for shear has been explained in detail.
When ratio of longer span to shorter span is greater than 2 than it is considered as one way slab, it rests on two supports and around 84% load is taken by short span where as 16% is taken by long span, main reinforcement is provided along short span and distribution steel is provided along long span

Dear sir, For dead load you calculated, 25*1*0.175 = 4.375 kN/m2 I think the unit should be kN/m 25 kN/m3 x 1m x 0.175 m = kNm2/m3 = kN/m Please verify

I had read lot of books about design for footing then I found some thing is missing them I came across "pillai and Menon" after ramamuthram and I found ur teaching so easy and understandable with code provisions.....plz work on designing solutions ( being str.engg ) it helps me. ....to get old knowledge back.....plz show: Column, slab, mat,raft,sloped,can't.slab.....and more designs and plz refer books with code provisions......

So confused...load unit is KN/m^2 and then using this unit, moment will come in KN only not KN-m!!!????.... Edit: if you are confused about it than this is the answer: Live load is in KN/m^2...and we have to multiply it with b(in case of slab analysis b is always 1m ) and hence the unit will be in KN/m...similarly for floor finish also multiply by b....

Hi sir When we design a RCC slab to determine the thickness of slab why we dont determine the thickness of it directly? I mean why we find an initial thickness for it by estimation at first and then we select a suitable thickness. Is there any rule to follow in estimation step?

Hello, initially we take it from L/d ratio as a guidance and than check for the d with respect to moment whether it is sufficient or no
