The important objective of earthquake engineers is to design and build a structure in such a way that damage to the structure and its structural component during the earthquake is minimize. The paper aims towards the dynamic analysis of RCC and Steel building with unsymmetrical configuration. For the analysis purpose models of G +9 stories of RCC and Steel with unsymmetrical floor plan is consider. The analysis is by carried by using F.E based software E TABS. Various parameter such as lateral force, base shear , story drift , story shear can be determined .For dynamic analysis time history method or response spectra method is used .Dynamic analysis should be performed for symmetrical as well as unsymmetrical building. Dynamic analysis can be in the form of full nonlinear dynamic time history analysis .If the RCC and Steel building are unsymmetrical , Torsional effect will be produce in both the building and thus are compared with each other to determine the efficient building under the effect of torsion.

Keywords: Dynamic effect, Seismic Design, Finite Element Analysis, Torsion.
