摘要：

This research investigates multiple objectives seismic damage evaluation procedures. Primarily, the Reinforced Concrete (RC) frame shear wall building has been designed using the Unified performance-based design (UPBD) method. The nonlinear dynamic analysis is performed considering spectrum compatible ground motions (SCGM) as per EC-8 demand spectrum at 0.45 g level and type B soil condition and it estimated the Damage index (DI) of the building by using Park and Ang method. It has been observed that this method is way too tedious and takes maximum time with the increase of the storey height. Hence, it is inappropriate for wide extensive investigation. Therefore, a new approach has been suggested to reduce the computational time as well as efforts in the case of complex structures to evaluate the global damage index (GDI). For this purpose, an 8-storey frame shear wall building has been investigated. In this present study, the considerations of three effective parameters i.e. inter-storey drift ratio (IDR), joint rotation, and optimum roof displacement have been merged to find the GDI of the building. In this study, it has been observed that the most damage happened on the ground storey floor compare to the remaining floors. © 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
