摘　　要：针对盒子结构无配套剪力墙的现状,提出带肋空心双板剪力墙,通过对5片不同墙肋宽度、厚度、是否布置横向肋的墙体进行低周反复荷载试验,研究了改进墙肋尺寸对此种墙体的破坏形态、滞回曲线、骨架曲线、强度退化、刚度退化及耗能能力等抗震性能指标的影响。研究表明:所有墙体抗震性能较好,不同改进墙肋的构造措施均可一定程度缓解墙体的破坏程度,提高墙体的承载能力及延性,延缓裂缝的出现,其中增加横向肋是最为有效提高墙体抗震性能的方法;钢筋与混凝土之间能够协同工作,具有良好的变形协调性能。In view of the current situation of box structures without supporting shear wall,this paper proposed a double-plate shear wall suitable for the new box structure system.Through low-cycle repeated load tests of five different structural forms of the walls,the influence of the improved wall rib size on the seismic performance,such as failure mode,hysteresis curve,skeleton curve,strength degradation,stiffness degradation and energy dissipation capacity of the wall,was studied.The results show that all the walls have good seismic performance,and different structural measures to improve the wall ribs can alleviate the damage degree of the wall to a certain extent.Adding transverse ribs is the most effective way to improve the seismic performance of the wall.The strain comparison curve shows that the steel bar and concrete can work together and have good deformation coordination performance.
