STUDY ON AXIAL COMPRESSIVE BEHAVIOR AND CALCULATION METHOD OF PRECAST SRC COMPOSITE TUBE SHEAR WALLS

College of Civil Engineering, He'nan University of Technology, Zhengzhou 450001, China

摘要

摘要: 为研究装配式钢-混凝土组合管(SRCT)剪力墙的轴压性能，完成了7个SRCT剪力墙试件的轴压性能试验，分析了试件的破坏形态、承载能力、位移延性、初始刚度等轴压性能。结果表明：SRCT剪力墙具有良好的轴压承载能力、刚度和变形能力，表现出良好的轴压承载性能；SRCT剪力墙轴压承载能力和初始刚度与距厚比成反比，延性与距厚比成正比；拉结筋布置形式对SRCT剪力墙的轴压承载力有一定影响，对初始刚度影响较小，拉结筋梅花形布置的SRCT剪力墙轴压承载力更高；侧面锚栓布置形式对SRCT剪力墙承载力有较大影响，随着侧面锚栓的加强，SRCT剪力墙承载能力增大；提出了考虑钢板局部屈曲和钢管对内膛混凝土约束作用的SRCT剪力墙轴压承载力和初始刚度计算方法，计算结果与试验值吻合良好。

Abstract: An experimental study was conducted on seven precast steel-concrete composite tube (SRCT) shear walls to evaluate their axial compressive behaviors. Performance of the test specimens was evaluated in terms of failure modes, load-bearing capacity, ductility and initial stiffness, etc. The test results show that SRCT shear walls have high bearing capacity, stiffness and ductility. They show good axial compression performance. The ratio of distance to thickness is inversely proportional to the load-bearing capacity and initial stiffness of the wall, and proportional to the ductility of the wall; The layout of the stud has some effect on the bearing capacity of the wall, but it has little effect on the initial stiffness of the wall. The bearing capacity of SRCT shear wall with the stud of quincunx arrangement is better; The arrangement of bolts has great influence on the bearing capacity of SRCT shear wall. With the strengthening of the bolts, the bearing capacity of the wall are enhanced. The calculation methods of vertical bearing capacity and initial stiffness of SRCT shear wall considering the local buckling of steel plate and the restraint effect of steel tube on the inner concrete are put forward. The proposed calculation values are in good agreement with the test values.
