This paper presents a simple and efficient analytical model for nonlinear response analysis of steel plate shear wall (SPSW) structural systems. The proposed model combines individual contributions of the boundary frame and the infill plate. It includes a nonlinear spring element that simulates the global response of the infill plate. The load‐deformation characteristic of this element is defined by a backbone curve and the pinched oriented Ibarra–Krawinkler hysteretic model. SPSW panels in the proposed model are differentiated as intermediate and end panels with two different backbone curves. Based on the theory of pure diagonal tension and experimental data, a basic backbone curve is first developed for the intermediate panel. For the end panel where the strength and stiffness of the infill plate are adversely affected by the flexibility of the anchor beam (the horizontal boundary element at the free end), the basic backbone curve is modified using appropriate strength and stiffness reduction factors. These factors are found by incorporating the strain energy of the anchor beam in the strain energy formulation of the theory of pure diagonal tension. Experimental results on several large‐scale SPSW specimens indicate that the proposed model reliably predicts the hysteretic behavior of SPSW structural systems.

钢板剪力墙结构体系非线性分析的简单模型

本文为钢板剪力墙（SPSW）结构系统的非线性响应分析提供了一种简单有效的分析模型。所提出的模型结合了边界框架和填充板的各个作用。它包括一个非线性弹簧元件，可模拟填充板的整体响应。该单元的载荷-变形特性由主干曲线和受压的定向Ibarra-Krawinkler滞回模型定义。在提出的模型中，SPSW面板分为具有两个不同主干曲线的中间面板和端面板。基于纯对角线张力理论和实验数据，首先为中间面板开发了基本的主干曲线。对于填充板的强度和刚度受锚梁（自由端的水平边界单元）的柔韧性不利影响的端板，可以使用适当的强度和刚度减小因子来修改基本主干曲线。通过将锚定梁的应变能纳入纯对角线张力理论的应变能公式中，可以找到这些因素。在几个大型SPSW标本上的实验结果表明，所提出的模型能够可靠地预测SPSW结构系统的滞后行为。通过将锚定梁的应变能纳入纯对角线张力理论的应变能公式中，可以找到这些因素。在几个大型SPSW标本上的实验结果表明，所提出的模型能够可靠地预测SPSW结构系统的滞后行为。通过将锚定梁的应变能纳入纯对角线张力理论的应变能公式中，可以找到这些因素。在几个大型SPSW标本上的实验结果表明，所提出的模型能够可靠地预测SPSW结构系统的滞后行为。
