In order to study the seismic behavior of precast concrete walls with different connection types for vertical reinforcements, the quasi‐static test on five concrete shear walls, including precast shear walls and cast‐in‐place shear wall was carried out. Test results showed that the failure mode of precast concrete walls was nearly the same as that of the cast‐in‐place concrete shear wall: in boundary elements at bottom of the shear wall, the vertical reinforcements yielded under tension, and the concrete was crushed under compression. The stress of vertical reinforcements could be effectively transferred by the sleeve‐mortar splicing. The specimen with hoop stirrup splicing had in‐plane rigid slide between the precast region and the cast‐in‐place region, whose ultimate drift ratio and energy dissipation capacity were lowest. The ultimate drift ratio of all specimens was larger than 1%. Based on results and analysis, recommendations for practical design for precast shear wall structures were proposed.

不同抗震技术的预制建筑混凝土墙的力学性能

为了研究具有不同连接类型的垂直钢筋的预制混凝土墙的抗震性能，对五个混凝土剪力墙（包括预制剪力墙和现浇剪力墙）进行了拟静力试验。试验结果表明，预制混凝土墙的破坏模式与现浇混凝土剪力墙的破坏模式几乎相同：在剪力墙底部的边界单元中，垂直钢筋在受拉状态下屈服，混凝土被压碎。在压缩下。竖向钢筋的应力可通过套筒砂浆接头有效地传递。带箍筋箍筋接缝的标本在预制区域和现浇区域之间具有面内刚性滑动，其最终漂移比和能量耗散能力最低。所有样品的最终漂移率均大于1％。根据结果​​和分析，提出了预制剪力墙结构实用设计的建议。
