摘　　要：提出了一种梯形正交加劲钢板剪力墙(TSW)结构,利用有限元软件ABAQUS创建了TSW模型,在验证了有限元建模方法的准确性后,进行了TSW与网格密肋钢板剪力墙(GSW)结构的非线性推覆对比和滞回性能对比分析,并对TSW进行参数分析。结果表明:在单调加载下的非线性推覆对比中,相较于GSW,TSW的初始刚度、峰值荷载和屈服荷载分别提升了9%、18%和26%;在水平往复荷载下的滞回性能对比中,相较于GSW,TSW的初始刚度、屈服荷载、峰值荷载和延性分别提高9%、26%、16%和5%。TSW对钢板剪力墙的面外变形的抑制效果大于GSW。内嵌钢板设置梯形加劲肋可以改善其过早发生整体屈曲。加劲肋厚度和加劲肋高度可以显著提高TSW的抗震性能,但加劲肋底边宽度对TSW的影响可以忽略不计。建议加劲肋厚度为6 mm、加劲肋高度不超过60 mm。A trapezoidal orthogonal stiffened steel plate shear wall(TSW)structure was proposed.The TSW model was created by using the finite element software ABAQUS.After verifying the accuracy of the finite element modeling method,the nonlinear pushover comparison and hysteretic performance comparison analysis of TSW and grid multi-ribbed steel plate shear wall(GSW)structure were carried out,and the parameter analysis of TSW was carried out.The results show that in the nonlinear pushover comparison under monotonic loads,compared with GSW,the initial stiffness,peak load and yield load of TSW increase by 9%,18%,and 26%,respectively.In the comparison of hysteresis performance under horizontal reciprocating loads,compared with GSW,the initial stiffness,yield load,peak load,and ductility of TSW increase by 9%,26%,16%,and 5%,respectively.The inhibitory effect of TSW on the out-of-plane deformation of steel plate shear wall is greater than that of GSW.The setting of trapezoidal stiffeners in the embedded steel plate can improve its premature overall buckling.The thickness and height of stiffeners can significantly improve the seismic performance of TSW,but the influence of the bottom width of stiffeners on TSW can be neglected.It is suggested that the thickness of stiffeners should be 6 mm and the height of stiffeners should not exceed 60 mm.
