摘要

为了研究波形钢板剪力墙的力学性能和耗能能力，设计了3个钢板剪力墙试件并进行了拟静力试验。试验结果表明，波形钢板剪力墙的滞回性能、承载能力和延性均优于平钢板剪力墙，且横向波形钢板的力学性能最优；同时分析试验的破坏形态发现，3个试件均是由于约束边缘构件H型钢柱刚度不足，导致试件发生失稳破坏，未能充分发挥内嵌钢板的力学性能；为了明确约束边缘构件与内嵌钢板刚度匹配关系，通过ABAQUS有限元分析软件建立12个模型进行数值分析，其中3个模型的几何参数与试验试件保持一致。对比数值分析结果和试验结果得出：有限元分析结果和试验结果吻合度较高；其余9个模型通过改变H型钢柱的翼缘宽厚比的方法，来改变H型钢柱与内嵌钢板的刚度匹配关系。分析结果表明，H型钢柱的翼缘宽厚比为13.9时，约束边缘构件与内嵌钢板的刚度匹配最优。

Abstract

In order to study corrugated steel plate shear mechanical properties and energy dissipation capacity, three specimens were designed and conducted quasi-static tests.The experimental results show that the hysteretic performance, bearing capacity and ductility of the corrugated steel plate shear wall are better than those of the flat steel plate shear wall, and the mechanical properties of the transverse wave steel plate is the best.At the same time, it can be obtained from the failure mode of the experiment that the three specimens were unsteady due to the out-of-plane deformation of the restrained edge member H-shaped steel column, which failed to give full play to the mechanical properties of the embedded steel plate.In order to study the stiffness matching relationship between constrained edge members and embedded steel plates, 12 finite element models were established for numerical analysis by the ABAQUS software, and the geometrical dimensions of 3 models were consistent with the experimental specimens.Comparing the numerical analysis results with the experimental results, it indicatess that the finite element analysis results are in good agreement with the experimental results.The remaining 9 models changed the stiffness matching relationship between the restrained edge member and the embedded steel plate by changing the flange width-to-thickness ratio of H-shaped steel column.The results show that when the flange width-to-thickness ratio of H-shaped column is 13.9, the stiffness matching between the restrained edge member and the embedded steel plate is optimum.
