The arc-shaped corrugated steel plate damper (ACSPD) has been developed to overcome buckling issues of conventional shear panel dampers. During earthquakes, dampers experience both in-plane and out-of-plane loading. However, the hysteretic performance of ACSPDs under bidirectional loading remains unclear. This paper investigates the mechanical and low-cycle fatigue performance of ACSPDs through cyclic quasi-static tests and numerical simulations, focusing on in-plane loading and 45° loading to represent unidirectional and bidirectional loading conditions, respectively. The results highlight notable differences in failure modes, mechanical behavior, and energy dissipation mechanisms under bidirectional loading. Despite these differences, ACSPDs exhibit effective energy dissipation even when subjected to bidirectional loading.

摘要

The arc-shaped corrugated steel plate damper (ACSPD) has been developed to overcome buckling issues of conventional shear panel dampers. During earthquakes, dampers experience both in-plane and out-of-plane loading. However, the hysteretic performance of ACSPDs under bidirectional loading remains unclear. This paper investigates the mechanical and low-cycle fatigue performance of ACSPDs through cyclic quasi-static tests and numerical simulations, focusing on in-plane loading and 45° loading to represent unidirectional and bidirectional loading conditions, respectively. The results highlight notable differences in failure modes, mechanical behavior, and energy dissipation mechanisms under bidirectional loading. Despite these differences, ACSPDs exhibit effective energy dissipation even when subjected to bidirectional loading.
