In recent trends, the architectural designs have many irregularities in the buildings that are unavoidable. These irregularities make the structure more vulnerable during disastrous natural event like earthquakes. In the present study, the behavior of irregular building during seismic event is studied. To assess the performance and vulnerability of the irregular building models considered, nonlinear static analysis is performed. The modelling and analysis is done using SAP 2000. The angle of incidence of seismic force is important in case of irregular buildings. The incidence of seismic action causes the building structure more vulnerable even if it is safe when analyzed and designed as per the design code provisions, hence it is essential to study behavior of the considered models, accounting the incidence angle of earthquake forces using parametric test. Nonlinear dynamic analysis has been carried out along different direction to determine critical angle of incidence by considering the different earthquakes which is comparable to response spectra of the Indian standard code.
