The main objective of earthquake engineers is to design and build a structure in such a way that damage to the structure during the earthquake is minimize. The paper gives the idea of seismic analysis of composite and RCC building with asymmetrical configuration. In the present work, steel-concrete composite with RCC options are considered for comparative study of G+9 storey commercial building which is situated in earthquake zone III and for earthquake loading, the provisions of

... 2002 is considered. The analysis is by carried by using ETABS Software. The parameter such as story drift, story shear and torsion is determined. For seismic analysis Equivalent static method and response spectra method is used. Seismic analysis should be performed for symmetrical as well as asymmetrical building. If the RCC and composite building have a symmetrical configurations, the torsional effect will be produce in both the building and are compared with each other to determine the efficient building under torsion. The results are compared and it is found that composite structures are better in several aspects.
