Different dynamic analysis methods are performed in order to evaluate the performance of a structure which is subjected to earthquake load. Among all the dynamic analysis methods, Non-linear Time History analysis method is more accurate. Because, it generates a real earthquake load on a structure and analyzes the response of the structure.
In this study, the structural behavior of RC building is observed subjected to an earthquake motion by Nonlinear Time History analysis method. Different parametric studies have been performed to investigate it’s responses during earthquake. These studies include variation in storey level and changing in the earthquake zones. Using BNBC-2015, a residential building is designed using ETABS 2015.1.0 software and then analyzed it using the same software. A ground motion El Centro (1940) is applied at the base of the structure and the seismic capacities at structural and element levels are evaluated according to the guideline of ATC 40 (1996). Formation of plastic hinges is used as the basis of local performance evaluation and storey drift is used as the basis for evaluating global performance.
It is found that, the designed building satisfies the acceptable performance criteria as per code ATC 40 (1996). It has been observed that both for varying sotrey level and different earthquake zones, the structure meets the performance objective in serviceability earthquake and design basis earthquake and passed all the criteria.
