RC slab / plate analysis 2D or 3D analysis
(OP)
Hi all. I have been studying the CSI safe program for RC slab/plates. One of the analysis option is to analyze the slab/plate in 2D (meaning only the following is considered: rotation at the two horizontal axis and translation in the vertical axis). I have always thought that RC slab/plates should only be analyzed as a 2D element, if we are considering gravity loads only. I believe that the axial loads on a slab caused by frame action is negligible and thus can be ignored in the analysis and design of the slab/plate.
My question is: when would the 3D analysis be useful? does SAFE wants us to consider the axial loads?

Many people are going towards the way of plate elements for the analysis of floor slabs but design-wise strips need to be considered. This is for strength, service and deflection calcs. I don't know what theory some of these FE-RC programs are applying to calculate out deflections.
