With increasing demand to achieve higher performance after strong earthquake shakings, novel high-performance systems have been developed. Self-centering rocking shear wall (SCRSW) is one of the high-performance structural systems which has been developed. To quantify the performance of SCRSWs, a robust performance evaluation model is needed. In this paper, the damage model developed in the companion paper (part 1) is adopted to evaluate the performance of 24 SCRSWs. The results of the performance evaluation are used to quantify the damage indexes (DI) for SCRSWs at different damage states. Design performance objectives, including the maximum and residual deformations corresponding to various performance levels are suggested based on the performance evaluation targeting different damage states. The proposed DI intervals and design performance objectives can be used by other researchers to design SCRSWs to achieve different performance objectives. |
