In this study the seismic performance of mezzanine flooring system is compared to various storey heights of the structure. For this purpose, seven storey structure was modelled using E-tabs. In this study three type model was taken they were regular structure, irregular structure and irregular structure on sloppy ground. In this three model mezzanine floors are located first at half storey height of the structure and then mezzanine floors are located at three-fourth height of the structure and its assumed that the building were located in the seismic zone V. In this study linear dynamic and nonlinear dynamic analysis is carried out using E-tabs. This method is used to study the response of the building under seismic loadings in terms of storey displacement, storey drift and as well as response spectrum analysis, time history analysis. The response for each type of building are studied and compared. Introducing mezzanine floors in the structure, its creates short column effects so this study also concentrated on how to overcome the short column effect economically. © IAEME Publication.
