Performance Based Seismic Design of R.C.C. Buildings with plan Irregularities

Performance- Based Earthquake Engineering (PBEE) in which the structural design is based on the predicted performance of the structure during an earthquake. Structural irregularities are important factors which decrease the seismic performance of the structures. Buildings which have structural irregularities may experience different drifts of adjacent stories, excessive torsion, etc. according to irregularity type and fail during an earthquake. In this work, performance based seismic design of buildings with plan irregularity is studied using Standard pushover analysis and Modal pushover analysis.. For present study, building models of (G+6) stories regular and irregular buildings of ‘L’ shaped, ‘C’ shaped and ‘T’ shaped are generated by a computer program ETABs (version 9.7.3). The buildings shape in plan is selected in such a way that the total area in plan remains same so that value of dead and live load remains almost same. Different parameters such as pushover curves, performance point.
