In India more than 54% of the land is endangered to earthquakes. Since prevention of earthquake occurrence is not possible hence the other option is to give priority to disaster mitigation and preparedness rather than restorative measure such as. Modifying the house type, building-design and plan in the vulnerable areas and making it compulsory to follow earthquake resistant code and designs. Recently different researchers have been broadly carried out studies on building having vertical or plan irregularity. However, most of the studies have been analyzed with focus on building resting on plain ground with plan irregularity without infill and diaphragm opening or performing experiments on building model for the static and dynamic loads. In other words, structural researchers are mostly concerned with the axial or shear behavior, Lateral stiffness, local compression effect, structure on plain ground, economic study, thermal comfort, soft storey building, building with opening or building with vertical irregularity.

Therefore, the present research work is to analyze 3D numerical models of G+14 multistory infill building with different shape of diaphragm discontinuity are constructed and performed the analysis by using software SAP 2000 (ver.16.0) using static nonlinear method. This paper highlights the comparing and investigating the performance of infill building with different shape of diaphragm discontinuity subjected to seismic load at performance point. The result of the analysis for displacement, base shear at performance point, storey drift, storey displacement and base moment have been studied and compared with the help of tables and graphs for all the structure models.
