研究了压剪复合荷载作用下无加劲钢板剪力墙填充钢板的受力状态。首先，将填充钢板分为三个区域，推导了各区域受压时的应力状态，并通过一系列数值算例验证了解析模型的准确性。其次，考虑重力荷载和相邻边柱剪力的共同作用，提出并讨论了各区域的应力状态。在此基础上，提出了边柱顶部重力荷载作用下无加劲钢板剪力墙的抗剪承载力计算方法。最后，对21个边柱轴力和不同钢板厚度的SPSW试件的抗剪承载力进行了预测。
This paper investigates the stress state of the infill steel plate for the unstiffened steel plate shear walls (SPSWs) under compression–shear combination load. First, the infill steel plate is divided into three zones, the stress state of each zone under compression is derived, and the accuracy of the analytical model is verified by a series of numerical examples. Second, considering the combination effects of the gravity load and shear force from the adjacent boundary columns, the stress state of each zone is proposed and discussed. Then the shear capacity of the infill steel plate for the unstiffened SPSWs with gravity load acting on the top of the boundary columns is proposed. Finally, the shear capacity of 21 numerical SPSW specimens with various axial stresses of the boundary columns and different steel infill plate thicknesses is predicted.
