Question what is the maximum allowable thickness of a rcc slab for a multi-storeyed building? which code of practice(including clause no.) can be followed for the thickness?
Answer Dear Sanzib
No explicit limit for maximum thickness exist, unless the need for ductility requirements force you to tune the slab thickness not to be stronger than the columns. The reinforcement of slab should be in consideration in this detailing process.
There is no limit for the thickness of the slab unless your casual design situation dictates you to limit. The loadings and their physical nature (dynamic or static)and also the span length may govern you to very large thickenesses. please let me know your opinion.
I can answer questions in Structural Engineering, Earthquake Engineering, Project Management and Project Control topics!
I am experienced in the area of earthquake engineering in electrical power industry, i.e. Lifeline Earthquake Engineering. My focus has been on structural seismic design of power installations. Recently I have got involved in project management in the category of constructional engineering.
