摘　　要：为探究轴压比和含钢率对X型骨架的装配式钢骨混凝土剪力墙抗震性能的影响,建立了不同参数的剪力墙数值模型进行数值试验,对比分析具有不同轴压比和含钢率的剪力墙数值模型在低周往复荷载下的数值试验结果。研究表明:增大轴压比,会降低X型骨架的装配式钢骨混凝土剪力墙的耗能能力与变形能力,并且加快了剪力墙刚度退化;增大腹杆的含钢率,可提高剪力墙的耗能能力、承载能力与刚度;增大端柱的含钢率,能显著提高剪力墙的承载力与刚度;综合对比分析,增大含钢率均可提升X型骨架的装配式钢骨混凝土剪力墙的抗震性能,但增大端柱含钢率较优。本研究对以后的理论研究和工程应用具有一定参考价值。To explore axial compression ratio and the steel ratio of the X-shaped prefabricated steel reinforced concrete skeleton shear seismic performance of impact, shear wall established numerical model parameters is different numerical experiments. Comparative analysis of the numerical test results of shear wall numerical models with different axial compression ratios and steel ratios under low-cycle reciprocating loads shows that increasing the axial compression ratio will reduce the prefabricated steel-reinforced concrete shear of X-frame The energy dissipation capacity and deformation capacity of the force wall,and accelerate its stiffness degradation;increasing the steel content of the web can improve the energy consumption,bearing capacity and rigidity of the test piece;increasing the steel content of the end column can significantly improve The bearing capacity and stiffness of the shear wall specimens;comprehensive comparative analysis,increasing the steel content can improve the seismic performance of the X-frame fabricated steel-reinforced concrete shear wall, but increasing the steel content of the end column is better. This research has certain reference value for future theoretical research and engineering applications.
