Performance-Based Seismic Design (PBSD) provides a methodology of understanding the risk to life, occupancy interruption and economic loss that may occur as a result of seismic events. The methodology has two primary concerns: appropriately quantifying the uncertainties associated with the performance evaluation process and satisfactorily characterizing the damage sustained by the structure. The paper aims at assessing the seismic performance of reinforced concrete structure subjected to lateral loads. For this, pushover analysis has been performed on a gravity-based designed Moment Resisting Frame (MRF). The effort involved in the performance evaluation of moment resisting frame relates to nonlinear modeling of reinforced concrete members. The study attempted to evaluate the performance of moment resisting frame by considering two possible plastic hinge locations: at the ends of members and at userdefined location. Various performance limit states have been verified using engineering demand parameters such as displacement, base shear, storey drift, interstorey drift and response modification factor. A performance-index has been evaluated for different limit states, which reflects the capacity of the structure against the applied lateral force. An attempt has been made to correlate damage state with different performance levels.
The experiences learned from the recent earthquakes, which happened across the world, raise the need to develop predictive methods of seismic design. The perspective design methods available in current seismic design codes are force-based. They are indirect with unknown reliability and are uneconomical (Hamburger, 2006). Performance-Based Seismic Design (PBSD) approach has proved to be a better alternative towards the perspective design approach if nonlinear modeling of Reinforced Concrete (RC) section is properly addressed. PBSD documents such as the ATC 40 (1996), FEMA 356 (2000), FEMA 440 (2005) and ASCE 41 (2006) have been provided in various Performance-Based Seismic Evaluation (PBSE) methodologies. These documents have provided various modeling and acceptance criteria for a nonlinear modeling of RC sections (Ghobarah, 2001; and Zameeruddin and Sangle, 2016).
