摘　　要：为研究格栅管式双钢板组合剪力墙在强震下的滞回性能,建立了可考虑格栅管式双钢板组合剪力墙构件中混凝土塑性损伤和钢板延性损伤累计的ABAQUS有限元模型,研究该结构在水平往复荷载作用下的滞回曲线、骨架曲线及破坏形态。首先采用原型试验验证了格栅管式双钢板组合剪力墙可考虑损伤累计的数值模型,从滞回曲线和骨架曲线考察了模型的计算精度,然后对轴压比、剪跨比等参数进行分析,为格栅管式双钢板组合剪力墙的工程应用提供参考。In order to study the hysteretic perfomance of grid-tube double steel plate composite shear wall under strong earthquake, the ABAQUS finite element model considering plastic damage of concrete and ductile damage of steel plate in grid-tube double steel plate composite shear wall was established. And the hysteretic curves, skeleton curves and failure modes of the structure under horizontal reciprocating loads were studied. Firstly, the numerical model of grid-tube double-steel-plate composite shear wall considering damage accumulation was verified by prototype test, and the computational accuracy of the model was evaluated from hysteretic curves and skeleton curves. Then, the axial compression ratio and shear-span ratio were analyzed. It could provide a reference for the engineering application of grid-tube double steel plate composite shear walls.
