摘　　要：为研究新型外包钢板内置钢筋桁架混凝土组合剪力墙的抗震性能,使用有限元软件ABAQUS建立符合实际试验情况的模型。依据已验证的有限元模型,建立12个不同参数的组合剪力墙模型进行往复加载分析,研究钢筋桁架直径、剪跨比等参数对新型外包钢板内置钢筋桁架混凝土组合剪力墙抗震性能的影响。结果表明:钢筋桁架直径的增大,可以显著增强组合剪力墙的延性与变形性能;随剪跨比的增大,峰值承载力逐渐降低,延性先提高后下降。In order to study the seismic performance of new type steel plate encased reinforced truss concrete composite shear wall,the finite element software ABAQUS is used to establish a model that conforms to the actual test situation.Based on the verified finite element model,12 composite shear wall models with different parameters are established for reciprocating loading analysis,and the effects of reinforcement truss diameter,shear-span ratio and other parameters on the seismic performance of new type steel plate encased reinforced truss concrete composite shear wall are studied.The results show that the increase of reinforcement truss diameter can significantly enhance the ductility and deformation performance of the composite shear wall;with the increase of shear-span ratio,the peak bearing capacity decreases,and the ductility increases first and then decreases.
