装配式钢板条带混凝土剪力墙抗震试验研究

摘要

设计制作了1个1/2现浇钢板条带混凝土剪力墙和1个1/2装配式钢板条带混凝土剪力墙试件,并在0.1轴压比下进行了低周反复加载试验研究.分析比较了两种试件的破坏形态、承载力、变形与延性、刚度、耗能能力等.试验结果表明,钢板条带可限制裂缝的发展,墙体出现分段裂缝,具有良好的抗震耗能能力和延性,装配式钢板条带剪力墙的螺栓连接能够有效传递应力,水平接缝具有良好的变形能力.%A 1/2 cast-in-place steel strip concrete shear wall and a 1/2 precast steel strip concrete shear wall specimens are designed and produced.And a low-cycle repeated loading test is completed at axial compression ratio of 0.1.The failure modes,bearing capacity,deformation and ductility,stiffness and energy dissipation capacity of the two specimens were analyzed and compared.The experimental results show that the steel strip can limit the development of cracks for the wall appearing segmented cracks.The two specimens have good seismic energy dissipation capacity and ductility,and bolts of precast steel strip concrete shear wall can effectively transfer stress.The horizontal seam has good deformation ability.
