Being highly indeterminate, the analysis of coupling slabs subjected to the effect of lateral loads due to wind etc. , in addition to gravity loads in tall buildings consisting of shear walls and floor slabs is a very complex task and therefore great difficulty is experienced when such slabs are designed. One of the possible solutions is the use of finite element method to find the elastic distribution of moments Mx, My and Mxy which could later be used to find the design moments and ultimately the steel areas required to reinforce different regions of the slabs. Nevertheless as is apparent from the following sections there is scarcity of information about the flexural behaviour of such slabs in the postelastic range. Therefore literature review pertaining to this particular aspect is presented in this paper so that a comprehensive programme could be prepared for experimental investigations in order to propose a relatively simpler conventional method for the analysis and design of these slabs.
