摘　　要：为研究装配式钢-混凝土组合管(SRCT)剪力墙的抗震性能,完成了4个足尺SRCT剪力墙试件的低周反复荷载试验,分析了试件的破坏形态、承载能力、滞回曲线、位移延性、刚度退化和耗能能力等。结果表明:SRCT剪力墙具有良好的承载能力、刚度和延性,表现出良好的抗震性能;随钢板厚度的增大,试件的破坏形态由钢板撕裂屈曲为主转为焊缝破坏为主,预制构件生产制作时需保证薄钢板与型钢连接的焊接质量,避免焊接破坏发生;0.2轴压比作用下,试件的屈服位移角的平均值为0.005 rad,极限位移角为0.013 rad,均高于现行规范限值;拉结筋间距200~250 mm范围内,适当减小拉结筋间距可提高剪力墙的延性及耗能能力。A quasi-static loading test was conducted on four full-scaled models of prefabricated steel-concrete composite tube(SRCT)shear walls to evaluate the seismic performance.The test results were analyzed in terms of failure mode,bearing capacity,hysteretic curves,ductility,stiffness degradation and energy dissipation capacity.The results showed that the SRCT shear wall had high bearing capacity,stiffness,ductility and energy dissipation capacity.As the thickness of the steel plate increased,the failure mode of SRCT shear wall changed from steel plate yielding to weld failure.Measures should be taken to ensure the welding quality of U-shaped steel and steel plates to achieve the design failure mode.The average value of the yield displacement angle of the specimens was 0.005 rad,and the average ultimate displacement angle was 0.013 rad,indicating that the deformation capacity of SRCT shear wall was higher than the specification limit.In the range of 200-250 mm spacing between stud-tie bars,properly reducing the spacing between stud-tie bars could improve the ductility and energy dissipation capacity of the shear wall.
