Abstract

Each multi-story building means a significant investment and as such multi-story building analysis is generally performed using more sophisticated techniques and procedure. Therefore, accepting modern ways to seismic analysis of multi-story buildings can be very valuable to structural engineers and researchers. Floor and roof systems act as a diaphragm to transfer the lateral load to the vertical load supporting elements like beams, columns, walls, etc. For simplicity in the dynamic analysis of a building, floors are assumed to be rigid in their own plane. This idea was built up 40 years ago which assumes that the whole floor moves as the rigid body motion; two translational and one rotational degree of freedom per each floor. The main purpose of this study was to carry out the effectiveness of the structure (highrise structure) against lateral loadings by providing a different diaphragm system to the frame. To fulfill this criterion, the authors have considered three types of structural systems: bare frame structure, structure with rigid diaphragm and structure with semi-rigid diaphragm. This will be considered in this study work by carrying out a comprehensive literature survey and analysis of different plans of buildings.
