Abstract
Due to irregular geometrical configurations of a building with irregular distributions of mass, stiffness and strength leads to damage at weak zone of the building. In reality, many existing buildings contain irregularity due to aesthetic and functional requirements. Damage to irregular structures caused by asymmetry in plan has been observed during many major past earthquakes. In the present study plan irregularity of high-rise building and seismic effect for these building is discussed. The structural analysis of reinforced concrete irregular frame building is done with the help of ETAB 2016. G+12 story buildings with plan of shape L, C, T, I and Y is selected. Equivalent static analysis is done for selected buildings. Lateral load analysis is done for seismic zone V. Comparative study of maximum displacement, maximum story drift and maximum base shear is done for all type of buildings. The results shows that the shape of building has significant effect in minimizing the displacement and drift of the building.
