［摘要］对三个不等肢耗能竖缝装配式剪力墙进行低周反复荷载试验，并与现浇剪力墙试件进行对比。结果表明，不等肢耗能竖缝装配式剪力墙整体工作性能良好，和现浇试件相比，其延性性能较高。竖缝中设置的阻尼器能够实现屈服耗能，提高结构的抗震性能，实现墙肢之间的连接；墙肢的不同会造成装配式剪力墙试件在两个加载方向承载力的差异，对结构的延性也有一定的影响，应尽量使竖缝两侧的墙肢较为接近，以获得较好的工作性能。

Abstract:The low-cycle reciprocating load tests were carried out on three prefabricated shear walls with unequal limbs and energy-dissipating vertical joints and the results were compared with the experimental result of one cast-in-place shear wall. The results show that the performance of the prefabricated shear walls with unequal limbs and energy-dissipating vertical joints is good, and the ductility is improved compared with that of the cast-in-place specimen. The damper set in the vertical joint can yielding and realize energy dissipation, improve the seismic performance of the structure, and realize the connection between the wall limbs. The difference of the wall limbs results different bearing capacity of the specimen in two directions, which also affects the ductility. Therefore, the wall limbs of the specimens should be close to each other to obtain better working performance.

Keywords:shear wall with unequal limbs;prefabricated;vertical joint;seismic performance;damper;ductility
