半刚性框架-大高宽比钢板剪力墙抗震性能研究

在半刚性框架-大高宽比钢板剪力墙体系中,半刚性框架和内填钢板均具有很好的延性和耗能性能,两者协同工作进行抗侧以防止结构在地震作用下破坏。为深入研究半刚性框架-大高宽比钢板剪力墙的力学性能,采用ANSYS有限元分析软件对结构进行数值分析,并考察框架节点形式,内填钢板高宽比、高厚比,柱轴压比和肋板刚度比等一系列参数对结构滞回性能的影响。根据内填钢板中心点在循环荷载作用下的面外变形,研究半刚性框架-大高宽比钢板剪力墙的屈曲性能和受力机理。

RESEARCH ON SEISMIC BEHAVIOR OF STEEL PLATE SHEAR WALLS WITH SEMI-RIGID CONNECTION FRAME AND LARGE ASPECT RATIO

Under the horizontal load,semi-rigid connection frame and the infill plate of steel plate shear wall can work together in the resistance to lateral force,both having good ductility and energy dissipation properties to prevent structural damage under seismic loading.To study deeply the mechanical properties of the steel plate shear wall with large aspect ratio and semi-rigid connection frame,ANSYS finite element analysis software is used for numerical analysis.The effect of a series of parameters on the hysteretic performance are studied,which include the ratio of height to width,height to thickness ratio,axial compression ratio and stiffness ratio of stiffener.According to the deformation of the center point under cyclic loading force,the structural buckling behavior and mechanism of resistance to lateral force are studied.
