两边连接屈曲约束钢板墙优化布置
Optimal layout of two-side connected buckling restrained steel plate shear walls
摘要
Abstract
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.关键词
