In the present study, the behaviour of setback buildings under seismic excitation is analysed using Finite element (FE) method using SAP2000. A model of G+9 storey RC building was considered with setbacks at different floor levels to introduce the vertical irregularities. Three different configurations of the building models, with varying setbacks, are analysed using different methods – 1) Response Spectrum Method (linear dynamic) as per IS 1893:2016 (Part-I), 2) Push over Analysis (non-linear static) using FEMA 356 and 3) Time History Analysis (non-linear dynamic). The response such as base shear, storey displacement, Angle of incidence, Time period, Column and beam moments are analysed in both X and Y directions and compared with the regular model. Effect of irregularities caused due to variation in plan and setbacks, on the response have been discussed, which governs the seismic vulnerability of setback RC buildings. |
