A Comparative Study on Cyclic Behavior of S-Shaped and U-Shaped Steel Plate Dampers
Linfa Wang
The widely used U-shaped steel plate damper (USPD), featured by large deformation capacity and excellent energy dissipation efficiency, is incapable of achieving multi-level seismic control due to single-stage energy dissipation. To tackle this issue, a new S-shaped steel plate damper (SSPD) derived from USPD and sharing identical geometric dimensions is presented, which exploits a bending-tensile yield mechanism to form double-stage energy dissipation behavior. This paper carries out comprehens
