Pushover Analysis of 21 Storey RC Shear Wall Building

during past earthquakes many of the buildings were collapsed due to failure of vertical members. Therefore, it is necessary to provide strong vertical member so as to sustain the design earthquake without failure. Shear wall is one of the lateral load resisting systems which can resist greater amount of forces. Pushover analysis is widely used for performance based design of new structures. In present study 2 models of 21 storey building were analyzed like shear wall as a shell element and shear wall as a column element. Analysis was carried out using ETABSv16. Time period obtained by dynamic analysis is compared. Pushover analysis is carried out using SAP2000 v18 on shear wall building (as a column element) as per ATC40 capacity spectrum method. User defined hinge properties are assigned to beam and column. Pushover analysis results are presented in terms of capacity, demand, performance point and pattern of hinge formation at performance point. This results help in identifying damage level of building.
