钢板剪力墙弹性抗侧刚度分析

ANALYSIS ON ELASTIC LATERAL-RESISTANT STIFFNESS OF STEEL PLATE SHEAR WALL

钢板剪力墙内嵌钢板的主要作用是抵抗水平荷载,其抗侧刚度的确定对分析整个结构体系在水平荷载作用下的结构反应有很重要的作用。对钢板剪力墙的弹性抗侧刚度进行了研究,首先在分析内嵌钢板与边缘框架之间相互作用的基础上,推导了钢板剪力墙的抗侧刚度理论表达式。其次,采用ABAQUS软件建立了多个算例的有限元模型;最后,将理论结果与有限元分析结果进行了对比研究,结果表明所推导的抗侧刚度的理论公式是精确可靠的。

The main function of the steel plate slotted in the steel plate shear wall is resisting horizontal forces, therefore, estimating its lateral-resistant stiffness plays a very important role in analyzing the reaction of the whole structure under horizontal forces. This paper analyzed the research on the elastic lateral-resistant stiffness of steel plate shear wall. Firstly, based on analyzing the interaction of the slotted-in steel plates and the boundary frame, the theoretic expression of the lateral-resistant stiffness of steel plate shear wall is derived. Next, some finite element models of samples were given by using ABAQUS. Finally, the results of analysis based on ABAQUS were compared with the theoretical ones, showing that the theoretic expression of the lateral-resistant stiffness of steel plate shear wall is accurate and reliable.
