In the present paper, effect of height of building on base shear, lateral forces and storey drift is evaluated by using STAAD software and the results are compared with IS1893 (Part1:2002). For these purpose seismic coefficient method (SCM) specified in IS1893 (Part1:2002) is taken into consideration and results are obtained in STAAD by SCM. The study includes the modeling of two buildings having plan areas 15 m x9 m and 25mx15m and the height is varied from 3m, 6m, 9m and 12m. The study is conducted by varying the geometrical properties of the structure but the seismic properties are kept constant. The buildings are located in zone II region. The results obtained for base shear and other design parameters obtained from STAAD software match with IS1893:2002. Spring mass model with the lateral forces are also plotted for the different buildings. Percentage change in storey shear for the different buildings is also evaluated. It can be observed that as the height and area of building increases the base shear and storey drift increases.
