摘要
为综合评价矩形螺旋箍筋约束波纹管浆锚连接的装配式混凝土剪力墙的抗震性能,对该剪力墙足尺试件进行了低周反复荷载试验,并与现浇试件进行对比.结果表明:矩形螺旋箍筋约束波纹管浆锚连接试件的破坏形态与现浇试件基本相同;由于水平拼缝的存在,两种试件的受力全过程的表现形式并不一致;两种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;两种试件的极限位移角分别为1/49和1/45,位移延性系数均为4.0,满足延性要求;相比现浇试件,矩形螺旋箍筋约束波纹管浆锚连接试件各阶段的承载力有所降低.若水平拼缝采用合理构造,装配式混凝土剪力墙结构可以达到与现浇结构相当的延性、承载能力以及抗震耗能能力.
In order to comprehensively evaluate the seismic behavior of the precast concrete shear wall with rectangular spiral stirrups-constraint grouted corrugated pipe connected to horizontal joints,the full-scale specimens of the shear wall was tested and compared with the cast-in-place specimens through a low-cycle loading experiment. The results show that the（ 1） the full-scale specimens follow the same failure pattern as the cast-in-place specimens do;（ 2） due to the existence of horizontal joints,the whole loading processes of the two kinds of specimens are different;（ 3） the hysteresis curves of the two kinds of specimens are both full with similar skeleton curves,and the energy dissipation capacities are also similar;（ 4） the two kinds of specimens are of the ultimate displacement angles of 1 /49 and 1 /45 respectively,and the displacement ductility factors are both 4. 0,which can meet the ductility requirements;（ 5） the load capacities of the full-scale specimens at different stages are lower than that of the cast-in-place specimens; and（ 6） precast concrete shear wall with reasonable horizontal joints is of the ductility,load capacity and seismic energy dissipation capacity similar to those of the cast-in-place specimens.
