中文摘要：

针对偏心支撑结构中耗能梁段过大的塑性变形会引起楼板严重破坏、修复难度较大的问题，提出了一种在x型偏心支撑中间内置钢板剪力墙的新型结构形式——偏心支撑式钢板剪力墙．首先，利用有限元数值模拟方法对偏心支撑式钢板墙结构与X形偏心支撑钢框架结构的抗震性能进行对比分析；然后，分析了中心钢板剪力墙的大小对结构滞回曲线、耗能系数的影响，并通过骨架曲线进一步分析了中心钢板剪力墙的大小对结构极限承载力、抗侧刚度及延性的影响．结果表明：偏心支撑式钢板剪力墙结构可以减小耗能梁段的耗能变形，从而减小楼板的破坏程度；同时它具有足够的承载力和优越的耗能能力．

英文摘要：

As link beams in eccentrically braced steel frame cause oversize plastic deformation and the repairing work of beam and floor after earthquake is heavy, this paper suggests a new braced steel frame system, eccentrically braced steel plate shear wall, adding a steel plate shear wall in the center of X-eccentrically braced steel frame. Firstly, the comparion of eccentrically braced steel plate shear wall and X-eccentrically braced steel frame on seismic performance is carried out via the finite element method. Then, the effects of concentrical steel plate shear wall size on hysteretic curves and energy dissipative coefficient have been investigated via the finite element method. Moreover, the horizontal bearing capacity, lat- eral stiffness and ductility at different concentrical steel plate shear wall size are further analyzed according to the backbone curve. Results indicate that the new system can lighten the breakage of the link breams, lighten repairing load after earth- quake, and have preferable ductility and enough bearing capacity.
