摘　　要：两边连接屈曲约束钢板墙的布置方式对结构体系的刚度、承载力和边缘构件的内力有显著影响。通过对两边连接屈曲约束钢板墙边缘梁的承载力需求进行理论分析,提出通过屈曲约束钢板墙交错布置的方式降低边缘梁的承载力需求。以10层3跨平面钢框架结构为研究对象,采用有限元分析的方法对两边连接屈曲约束钢板墙的优化布置进行研究,通过水平荷载作用下结构荷载-位移曲线和边缘梁内力的对比,分析采用不同布置方案时结构体系的受力性能。结果表明:单跨布置屈曲约束钢板墙时,单块钢板墙交错布置、钢板墙二一间隔布置、两块钢板墙交错布置等方案可作为优选方案;多跨布置屈曲约束钢板墙时,边跨交错布置、人字形布置、X形布置可作为优选方案。采用提出的屈曲约束钢板墙优化布置方案可以使结构具有较大的侧向刚度,同时减小边缘梁的内力。The layout of two-side connected buckling restrained steel plate shear wall(BRW) has significant effect on the stiffness and bearing capacity of structure and the internal forces of boundary elements.The capacity demand of boundary beams for two-side connected BRW was analyzed theoretically,and the staggered layout of BRWs was proposed to reduce the bearing capacity demand of boundary beams.Then,a plane steel frame structure with ten stories and three spans was designed as the basic structure,and the mechanical performance of structures with different BRWs layout schemes was studied by finite element analysis method.By the comparison of load-displacement curve of structure under lateral load and internal forces of boundary beams,better layout schemes of BRWs were proposed.For single-span layout scheme,staggered layout of one BRW,alternate layout of one BRW and two BRWs,and staggered layout of two BRWs in different stories have obvious advantages.For multi-span layout scheme,staggered layout of one BRW in the side span,herringbone layout of BRWs and X-shaped layout of BRWs can be used as the preferred scheme.The proposed optimal layout scheme of BRWs can make the structure have larger lateral stiffness and lower internal forces of boundary beams.
