The paper aim towards the analysis of Symmetric and Asymmetric building using a software STAAD.PRO. The two buildings are considered in the study, one is rectangular in shape and other is ?L? in shape and both are been analyzed by linear Static method and Response Spectrum method. The two plans are studied for different variation of height i.e., G+5, G+10, G+15 and G+20 and seismic properties are kept similar for both the buildings. The parameter evaluated are Base Shear, Story displacement, Story shear, Story drift and Time period. The manual calculation of Base shear is obtained and compared with the STAAD result as per code IS 1893:2002. The each parameter is studied for different height and checked the difference between Symmetric and Asymmetric building. The paper also includes what will be the effect, if the height of building increases due to a seismic analysis.
