【摘要】 对两个1/3比例的方钢管混凝土框架-薄钢板剪力墙试件进行了拟静力试验研究。其中,试件SPSW-CB中钢板剪力墙仅与框架梁连接,试件SPSW中钢板剪力墙与框架梁柱均连接。结果表明:方钢管混凝土框架-薄钢板剪力墙具有较高的侧向承载力、良好的耗能能力及延性,符合抗震设防理念,能够达到双重抗震设防目标。两边连接的钢板剪力墙显著降低了结构的侧向承载力、刚度及耗能能力。在钢板剪力墙自由边设置加劲肋虽然可有效限制钢板剪力墙平面外变形,但加劲肋强弱会显著影响"拉力带"的充分开展,进而影响结构的抗震性能。加劲肋及其连接的可靠性是保证两边连接钢板剪力墙优异性能的必要条件。更多还原

【Abstract】 The quasi-static tests on two 1 /3 scale concrete-filled square steel tubular frame-thin steel plate shear walls specimens were conducted.The specimen SPSW is connected to both beams and columns of the frame,but the specimen SPSW-CB is connected to the frame beams only.The results show that concrete-filled square steel tubular frame-thin steel plate shear walls have high lateral-resisting capacity,excellent energy dissipating capacity and ductility,and agree with the concept of seismic prevention and achieve the aim of two-way seismic protection.Steel plate shear walls with both sideconnections significantly reduce structural lateral-resisting capacity,stiffness and energy dissipating ability.Stiffeners installed on the free edges can effectively limit the out-of-plane deformation of steel plate shear walls,but the strength of stiffeners can significantly affect the full development of tension field,having compact on structural seismic behavior.The necessary requirement which secures the excellent properties of steel plate shear walls is that the vertical surrounding members and its connections do not fail.更多还原
