摘　　要：为了验证多腔式双钢板组合剪力墙的抗震优越性,制作了钢筋混凝土剪力墙和多腔式双钢板组合剪力墙,通过低周反复水平荷载试验,获得了两种剪力墙的破坏形态、滞回曲线和骨架曲线;建立了ABAQUS有限元模型,进行了多腔式双钢板组合剪力墙的抗震试验仿真分析,模拟了其破坏形态和累计损伤状态。结果表明:多腔式双钢板组合剪力墙具有承载力大、延性好、耗能强等优点;构件最终破坏时,虽然管内混凝土受压塑性变形发展较大,导致外侧双钢板明显臌胀,但管内混凝土并没有压碎,可以继续工作承担荷载;构件的最终破坏形态为受拉钢板撕裂破坏,属于延性破坏。In order to verify the seismic superiority of multi cavity double steel plate composite shear wall,a reinforced concrete shear wall and multi cavity double steel plate composite shear wall were made,and the failure modes,hysteresis curves and skeleton curves of two shear walls were obtained through low cycle repeated horizontal load tests.The ABAQUS finite element model was established to simulate the seismic test of multi cavity double steel plate composite shear wall,and its failure mode and cumulative damage state were simulated.The results show that the multi cavity double steel plate composite shear wall has the advantages of large bearing capacity,good ductility and strong energy consumption.When the component is finally damaged,although the compressive plastic deformation of the concrete in the pipe develops greatly and leads to the obvious heave of the outer double steel plate,the concrete in the pipe is not crushed and can continue to work and bear the load.The final failure form of the component is the tearing failure of the tensile steel plate,which is a ductile failure.
