| 摘要： | In this paper, an innovative low- yield-point corrugated steel plate damper (LCSPD) was proposed, which consisted of two corrugated webs as the shear component and two outer corrugated plates as the bending component. Four LCSPDs were studied by varying the corrugation directions and arrangement forms. The lateral strength, energy dissipation, ductility, hysteretic behavior, and equivalent viscous damping coefficient of the LCSPDs were estimated by quasi-static tests. A finite element analysis was carried out based on the variables of web thickness and aspect ratio, and the validity of the finite element analysis was confirmed by comparing the results of the model with the experimental results. Comparing the horizontal low-yield- point corrugated steel plate dampers (LCSPD_H) with the vertical low-yield-point corrugated steel plate dampers (LCSPD_V), Damper specimen LCSPD_H exhibited better energy dissipation and ductility. Finally, a simplified formula was proposed to estimate the shear- carrying capacity of the LCSPDs, and the calculated results agreed well with the experimental results.
