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 embedded in the shear wall is to resist the horizontal load. The determination of its lateral stiffness plays an important role in analyzing the structural response of the whole structural system under the horizontal load. Based on the analysis of the interaction between the embedded steel plate and the edge frame, the theoretical expression of the anti-side rigidity of the steel plate shear wall is deduced. Secondly, a finite element model of several examples was established by using ABAQUS software. Finally, the theoretical results were compared with the results of finite element analysis. The results show that the theoretical formula of anti-side stiffness deduced is accurate and reliable.
