为了研究新型全装配式剪力墙结构体系中水平接缝的可行性及抗震性能,制作了2个试件并分别进行单调加载试验与低周反复加载试验.在试验的基础上研究了该全装配式剪力墙的荷载-位移曲线、承载能力、延性性能、抗侧刚度、钢筋应变、连接钢框的应变分布以及连接钢框与内嵌边框之间的相对滑移等.试验结果表明:试件具有较好的承载能力及延性,位移延性系数达3.7以上;在整个试验过程中,除受压端外,连接钢框中的正应力及剪应力远小于其屈服强度;试件受压端内嵌边框与连接钢框之间发生了一定的相对滑移,达1.13 mm,而受拉端二者之间未发生明显的相对滑移.该全装配式剪力墙结构体系的水平接缝安全可靠,抗震性能良好,方案可行.
In order to study the feasibility and anti-seismic performance of horizontal joints in the new fully assembled shear wall structure system, two specimens were made and subjected to monotonous loading test and low-cycle loading test respectively. On the basis of the experiments, Load-displacement curve, load carrying capacity, ductility performance, lateral rigidity, strain of steel bar, strain distribution of connected steel frame and relative slip between steel frame and embedded frame, etc. The test results show that: The test piece has good bearing capacity and ductility, displacement ductility coefficient of 3.7 or more; in the whole test process, in addition to the pressure end, the connection of steel frame is far less than the normal stress and shear stress yield strength; specimen compression There was a relative slip between the inner frame and the connecting steel frame, reaching 1.13 mm, while no obvious relative slip occurred between the two ends of the tension frame.The level of the fully assembled shear wall structural system Seamless security, seismic performance is good, the program is feasible.
