Abstract
Recently earthquakes have shown that the irregular distribution of mass, stiffness and strengths may cause serious damage in structural systems. Due to several reasons structures acquire asymmetry hence Seismic demand in peripheral elements is enhanced. Torsional behaviour of asymmetric building is one of the most frequent causes of structural damage and failure during strong ground motions. A study on the influence of the torsional moment effects on the behaviour of structure is done by using Response spectrum method. Then a simplified nonlinear pushover analysis has been used to find structural descriptors required in seismic vulnerability assessment. Deformation demand for different story for low-medium rise framed building has been found by using software SAP2000.
