| 摘 要： | 基于带缝钢板剪力墙的基本受力特点和变形特征，提出了一种弹塑性简化分析模型，并分别定义了模型的几何参数与非线性参数。为验证简化模型的正确性，分别对带缝钢板剪力墙以及钢框架带缝钢板剪力墙结构进行Pushover分析。分析结果表明：简化模型计算得到的荷载位移曲线与试验及有限元分析结果较为接近，可反映带缝钢板剪力墙的主要受力特征；简化模型可较为准确地反映协同工作时墙板对周边框架的附加作用力。

| Abstract: | Based on the mechanism of steel slit wall, a simplified elasto plastic analytical model which allows for nonlinear dynamic and static analysis was proposed. The parameters of simplified model related to configuration and nonlinear behavior were defined. In order to validate the simplified model, the pushover analysis of steel slit wall and a frame with steel slit wall were conducted. The results show that the load displacement curves obtained from simplified models, experiments and FEM are similar. The proposed model can fully represent the mechanism of steel slit wall, and it can correctly predict the internal forces and deformations of each member in the model. |
