Effect of Seismicity on the Seismic Resilience of a R.C. Building
This study was carried out to evaluate the functionality of an existing reinforced concrete structure under various ground motions along with its seismic resilience. An existing high-rise G + 10 storey reinforced concrete building which was designed for a specific ground motion with peak ground acceleration (PGA) of 0.36 g was subjected to various seismicity with respect to different ground motions of PGA ranges from 0.10 to 1.70 g. For each case, the performance level and structural damage ratio were estimated by performing nonlinear static pushover analysis. The influences of different ground motions on the structural functionality and seismic resilience were examined using three recovery functions namely, linear, trigonometric and exponential. The result shows that the maximum number of hinges formed with the performance level close to or just exceeding the level of collapse prevention at the maximum considered PGA of 1.50 g and 1.70 g with loss of resilience up to 36.25%. The maximum level of PGA that the existing building would withstand along with likelihood of recovery has been obtained.
