摘　　要：从环保角度提出一种钢木组合形式的两边连接防屈曲钢板剪力墙。基于已有的研究成果,设计两个试件,一个是没有木盖板约束的钢板剪力墙,另一个是覆盖木板作为钢板面外屈曲约束的钢板剪力墙。对试件采用位移控制加载方式进行拟静力试验,得到试件的滞回曲线。根据试验结果,分析了试件的骨架曲线、刚度退化和耗能能力。试验结果表明,木盖板抑制钢板屈曲效果较好,能够有效减小鼓曲声音;与无木盖板试件相比,有木盖板试件具有更高的承载力和更强的耗能能力。在试件破坏后,对试件进行拆卸,发现钢板腹部木盖板覆盖区域能够保持平整,拆卸后的木盖板在加载后也能保持完整。采用软件ABAQUS进行有限元分析,模拟结果和试验结果吻合,验证了模型的可行性。From the angle of environmental protection,a kind of steel and wood combined form was put forward,which connects the two sides of anti-buckling steel plate shear wall.Based on the existing research results,two specimens were designed,one was a sheet-plate shear wall without the restriction of wood cover plate,the other was a sheet-plate shear wall covered with wood as the restriction of external buckling of steel plate.The hysteretic curves of the specimens of specimens were obtained through the pseudo-static test with displacement controlled loading method.Based on the test results,the skeleton curve,stiffness degradation and energy dissipation capacity were analyzed.The test results show that the wood cover plate has a better effect on suppressing the buckling of the steel plate,and can effectively reduce the sound of buckling.Compared with the specimens without wood cover plate,the specimens with wood cover plate has higher bearing capacity and stronger energy dissipation capacity.After the specimen was destroyed,the specimen was disassembled,and it was found that the area covered by the wood cover plate in the belly of the steel plate could keep flat,and the removed wood cover plate could also keep intact after loading.The finite element analysis was carried out by software ABAQUS,and the simulation results are consistent with the experimental results,which verify the feasibility of the model.
