I have a query regarding manual slab design, whether the co-efficient method of slab design given in ACI 318-63 considers role of supporting beam stiffness? I have gone through the code and could not find that the moment co-efficients are co-related with supporting beam stiffness. But whenever the beam stiffness will be varied, there would certainly be variation of moments in slab determined by aforesaid method in ACI 318-63.
Exceptionally, I have seen somewhere on a webpage that for applicability of co-efficient method of slab design given in ACI 318-63, the slab has to be supported by walls or STIFF BEAMS? The question is again that HOW MUCH STIFF BEAMS??
Expert opinions shall be appriciated.
