    摘要:

    为综合评价水平拼缝采用竖向钢筋浆锚搭接的装配式混凝土剪力墙抗震性能,采用2个装配式和1个现浇的足尺试件进行低周反复荷载试验.试验结果表明:对于破坏形态,装配式混凝土剪力墙内墙试件与现浇试件基本相同,装配式混凝土剪力墙外墙试件与现浇试件有区别;各试件的滞回曲线均较饱满,骨架曲线走势基本一致,耗能能力接近;各试件极限位移角1/56~1/49,位移延性系数均为4;装配式混凝土剪力墙试件较现浇试件初期刚度有所降低,外墙试件水平拼缝上移后,承载能力有所提高.

    Abstract:

    To comprehensively evaluate the seismic performance of precast concrete shear wall with vertical reinforcements grouted in holes and spliced indirectly in horizontal connections, two fabricated and a cast-in-place concrete shear wall with full scale specimens were tested under low cyclic loading. The test results show that the concrete interior shear wall specimens (JN) is basically the same as the cast-in-place specimen (XJ) in failure modes, but the concrete exterior shear wall specimen wall (JW) is different with the XJ. The hysteresis curve of the specimen is full, the trend of the skeleton curve is basically the same and the capacity of the energy dissipation is close. The ultimate displacement angle of each specimen is 1/56-1/49 and the displacement ductility factor are 4. The initial stiffness of JW, JN are lower than the XJ, and the force behavior is improved in exterior wall specimens (JW) with the setting position of horizontal connections moved up.
