摘要： 为明确装配式剪力墙结构水平连接的传力机理,获得更优异的耗能能力,提出一种新型装配式剪力墙结构。针对此结构,设计制作4片缩尺比例为1∶1.54的不同螺栓配置数量、轴压比和边缘构件纵筋配筋率的新型装配式剪力墙结构模型,完成单向往复/单调加载试验。4片试件破坏模式相似,墙体保持弹性状态,且未发现明显裂缝;之后墙体混凝土发生破坏,裂缝多开展于1/3墙高下侧,最终破坏时沿墙身对角线向墙角贯通。轴压比/边缘构件纵筋配筋率减小导致试件各特征荷载降低。试验结果表明,增加螺栓配置数量虽然对试件的特征荷载影响不大,但能有效限制墙体侧移,提高试件的整体性和水平连接装置的传力性能;新型装配式剪力墙具有更强的变形能力,极限承载力与现浇墙体基本一致。
