Civil Engineering structures are designed to withstand environmental forces like an earthquake, along with gravity loads. These forces are random and dynamic in nature. Therefore the response of the structure is also dynamic and that is what causes the unsafe and uncomfortable conditions. So, performance-based analysis of the structure is required which can be achieved by Incremental Dynamic Analysis (IDA) as well as static pushover analysis (SPA). But, the incremental dynamic analysis is quite accurate and actual response of the structure of the structure from the particularly considered earthquake can be obtained by this method. It involves performing a series of nonlinear dynamic analyses in which the intensity of the ground motion selected for the collapse investigation is incrementally increased until the global collapse capacity of the structure is reached. In the present work, incremental dynamic analysis of reinforced concrete G+6 and the G+11 building is carried out. IDA curves are developed with respect to peak ground acceleration. Performance stages of the buildings such as yielding and collapse are defined with respect to peak ground acceleration of the considered earthquake from the IDA curve. Building susceptibility that is whether the building can sustain the particularly considered earthquake or not is found out using IDA. Also, serviceability criterion for inter-story drift ratio from IS 1893:2002 is checked from the IDA. Static pushover analysis of both the G+6 and G+11 building is also carried out. From the static pushover analysis, the graph of base shear to top displacement is plotted. From the graph, the base shear capacity of the building is found out. The base shear capacity of both the buildings is also found out using IDA and capacity curve of base shear to top displacement from IDA is compared with that of SPA.
