四角钢连接钢框架-钢板剪力墙结构抗震性能研究

基于半刚接框架-钢板剪力墙试件的低周反复加载试验，采用ANSYS有限元软件对其滞回性能进行了数值模拟。分析循环荷载作用下试件的滞回性能及承载能力，考察其应力、变形发展历程、耗能机理和破坏模式。试验和有限元分析结果均表明：内填板的设置缓解了节点区自身的延性要求，框架和钢板墙协同工作良好，结构体系耗能优异，安全储备高，是一种理想的抗侧力结构体系。有限元模拟结构应力和变形发展历程与试验结果基本吻合。由于初始偏心、焊接残余应力等原因，弹性工作阶段，有限元分析的峰值荷载与试验值比较接近；进入塑性阶段，有限元分析的峰值荷载比试验值大，滞回环更饱满。

Seismic behavior of four-angle-connection steel frame structure with steel plate shear walls

Based on the cyclic loading test, the finite element analysis on the hysteretic behaviors of the semi-rigid composite steel frame with steel plate shear wall was conducted to study the load carrying capacity, hysteretic behavior, stress and deformation development process, energy dissipation mechanism and failure mode. The results of analysis and test indicate that the requirement on the joint ductility is lowered by using infilled panels. The cooperative work between the frame and the shear wall is well. It’s an ideal lateral force resisting structural system, which has excellent energy consumption and high safety margin. The finite element simulation of structure stress and deformation development course agrees well with the experimental phenomena. Due to the initial eccentricity, welding residual stress and other reasons, the finite element analysis results of the peak load is close to the test results at elastic stage. The finite element analysis of the peak load is higher than the test results, and the theoretical hysteresis loop is plumper.
