Earthquake design plays major role in designing of any structure. The base shear is developed during an earthquake in a structure. The base shear is calculated by using the codes IS 1893:2002 (Part–1). The study includes the calculations of storey shear, storey drift and storey displacement of G+14 building which is situated in zone-5 with different irregularities. Irregularities are crucial in studying the seismic behavior of building. The irregularities considered are mass irregularity and vertical geometric irregularity. The mass irregularity has first floor without masonry wall and rest of floor with infill masonry wall i.e. soft storey and vertical geometric irregularity has uneven geometry in vertical position & shape of building. In very severe earthquake zone, structure fail due to high lateral loads in this project lateral loads are considered in both direction (EQX & EQY). The modelling and calculations of building are done using ETABS.
