Review on Recent developments in the performance-based seismic design of reinforced concrete structures

Abstract

The performance-based seismic design was suggested to overcome the limitations of force-based seismic design methods used for addressing the inelastic behavior and cyclic loading effects in reinforced concrete structures. The suggested method permits buildings to be designed with a realistic and reliable understanding of the risk to life, occupancy, and economic loss that may result from future seismic events. The design has two primary goals: appropriately quantifying the uncertainties associated with the performance evaluation process and satisfactorily characterizing the associated structural damage for direct incorporation into the design or performance evaluation methodology. This study reviewed recent developments in performance-based seismic design by defining the performance objectives (levels), evaluation techniques, and assessment procedures. In addition, the current state-of-practice in performance-based seismic evaluations were compared. In contrast to the performance evaluation procedures of previous studies, in which the pros and cons were highlighted, the performance evaluation procedure of the present study was implemented for force-based design structures. A damage index that was expressed using nonlinear responses obtained in the output of the procedure was introduced. A possible integration of the damage value with the performance level was proposed.
