摘要:本文通过对一个轴压比为0.18的预制混凝土剪力墙和现浇对比墙的拟静力试验，研究了直螺纹灌浆套筒连接的装配式剪力墙的抗震性能。结果表明：直螺纹灌浆套筒可以有效地传递钢筋之间的应力，使套筒上下钢筋协调工作。现浇和预制剪力墙试件均属于压弯破坏，竖向钢筋受拉屈服，混凝土受压破坏。但两者破坏形态有所差别。预制试件滞回曲线较饱满，极限位移角1/48，达到目前规范的要求。水平承载力是现行公式计算值的1.2倍以上，可用现行公式计算试件的压弯承载力。

Abstract: Quasi-static tests of a pre-cast reinforced concrete shear wall specimen and a cast-in-place comparasive specimen with axial compression ratio of 0.18 wer
e introduced. The vertical reinforcements of the specimen were spliced by thread-grout sleeves. The test results indicate that the thread-grout sleeves can transfer s
tresses. For the pre-cast wall specimen，the vertical reinforcements yield in tension and the concrete fails in compression. The failure mode of the pre-cast wall spe
cimen is different from that of the cast-in-site wall specimen. The lateral load-displacement hysteretic curve of the pre-cast wall specimen is plump，and the ultimat
e drift ratio is 1 /48. The current code formulas are suitable for calculating the compressive strength of the pre-cast shear walls.
