Performance Based Analysis of RC Moment Resisting Frame

The objective of performance based seismic design (PBSD) is to design structures so that they have predictable seismic behavior. Performance-based analysis evaluates how the building will perform in given potential hazard. In performance-based design, it is an important part of the design procedure to identify and assess performance capability of building and guide the many decisions that must be made. In this paper pushover analysis of multi-storey (G+5), (G+8), (G+11) RCC building has been done. Pushover analysis is a modern and excellent tool for performance-based analysis due to its accurate seismic assessment of the structure. The pushover analysis is performed using SAP2000 software. The results obtained after performing pushover analysis are compared in terms of parameters like base shear, storey displacements, spectral acceleration, time period and spectral displacement. From analysis results obtained, it is seen that base shear and spectral acceleration decreases, whereas displacement, spectral displacement is increased with the increase in number of storey. The seismic response of RC building frame in terms of performance point and the effect of earthquake forces on multi story building frame with the help of pushover analysis is carried out in this paper.
