摘　　要：为了研究多孔蝴蝶形钢板剪力墙的抗震性能,对4个足尺多孔蝴蝶形钢板剪力墙试件进行了低周反复加载试验。在蝴蝶杆腰宽比控制在0.4的前提下,研究了钢板厚度和开孔率对多孔蝴蝶形钢板剪力墙滞回性能、承载力和耗能性能的影响。试验结果表明:多孔蝴蝶形钢板剪力墙具有良好的抗震性能,是一种较理想的抗侧力构件和耗能构件;多孔蝴蝶形钢板剪力墙的最终破坏模式为钢板最外侧蝴蝶杆端部撕裂;随着钢板墙厚度的增大和钢板开孔率的减小,试件的抗侧刚度及承载力增大,耗能量增多。In order to study aseismic performance of porous butterfly-shaped steel plate shear wall,low cycle cyclic loading tests of 4 full-scale specimens were conducted.On the premise of the waist width ratio of butterfly bar being controlled at 0.4,effects of steel plate thickness and opening rate on hysteretic performance,load-bearing capacity and energy dissipation performance of porous butterfly-shaped steel plate shear wall were studied.The test results showed that porous butterfly-shaped steel plate shear wall has good aseismic performance and is an ideal anti-lateral force component and energy dissipation component;its ultimate failure mode is end tearing of butterfly rod on the outermost side of the steel plate;with increase in thickness of the steel plate wall and decrease in its opening rate,lateral stiffness and load-bearing capacity of specimens increase and their energy consumption increases.
