Abstract:

Many buildings in the present scenario have irregular configurations both in plan and elevation. This in future may be subjected to devastating earthquakes. So it is necessary to enhance the seismic performance of asymmetric buildings by using seismic control techniques to control the rotational induced torsion due to the asymmetric behaviour of the structure. In the present study, asymmetric buildings have been taken into account to control the seismic response of the structure. The present study is on the nonlinear time history analysis, considering the effect of use of shear wall and base isolation system. The RCC moment resisting frame is subjected to nonlinear time history analysis (NLTHA). The analysis engines used for the analysis and design are SAP 2000 version 16[3]. In the study, storey drifts, base shear, torsional moment and storey displacement of the structure were studied. The results indicate that significant effect of the base isolation was observed on the storey drift, base shear, storey displacement and torsional moment of low rise asymmetric buildings and significant effect of the shear wall was observed on the same responses of high rise asymmetric buildings.
