摘要

为研究波形钢板剪力墙的力学性能，进行了竖向和水平波形钢板剪力墙的试验研究，试验结果表明：水平波形钢板剪力墙的承载能力和滞回性能均优于竖向波形钢板剪力墙。试件均为纯钢构件，在制作、运输及安装过程中，易产生局部的几何变形，后续通过ABAQUS有限元分析软件建立10个有限元模型，考察不同初始缺陷大小对波形钢板剪力墙力学性能的影响，并与试验结果进行对比。通过对比结果分析得出以下结论：初始缺陷是波形钢板剪力墙建模分析时不可忽略的因素；随着初始缺陷峰值的增大，竖向和水平波形钢板剪力墙的承载力下降速率均随之增大，当初始缺陷峰值为腹板高度的1/250时，与完善剪力墙模型相比，其承载力分别下降了19%和9.5%；添加同样幅度的初始缺陷，其对竖向波形钢板剪力墙的力学性能影响远大于对水平波形钢板剪力墙力学性能的影响。

Abstract

In order to study the mechanical properties of corrugated steel plate shear wall， the experimental study of vertical and horizontal corrugated steel plate shear walls was carried out. The results show that the bearing capacity and hysteretic behavior of horizontal corrugated steel plate shear walls were better than that of vertical walls. The test pieces are all pure steel members， and local geometric deformation is easy to occur during the production， transportation and installation process. Then ten finite element models were established by ABAQUS finite element analysis software to investigate the effects of different initial defects on the mechanical properties of corrugated steel plate shear walls and compared with the experimental results. Through the analysis of the comparison results， the following conclusions are drawn： the initial defect is a factor that cannot be ignored in modeling and analysis of corrugated steel plate shear wall； With the increase of the peak value of the initial defect， the decrease rate of the bearing capacity of the vertical and horizontal wave steel plate shear walls increases. When the initial defect peak value is 1/250 of the web height， the bearing capacity of the shear wall model decreases by 19% and 9.5%， respectively， compared with the perfect shear wall model； The effect on the mechanical properties of vertical corrugated steel plate shear wall is much greater than that of horizontal corrugated steel plate shear wall by adding initial defects of the same amplitude.
