摘要

摘要: 为研究带构造边缘构件的T形装配整体式双面叠合剪力墙的抗震性能，完成了两个T形足尺剪力墙试件的拟静力试验。试验结果表明：在0.2轴压比下，叠合试件与现浇试件均表现为典型的弯剪破坏特征；与现浇试件相比，叠合试件翼缘受拉和翼缘受压时的极限承载力分别降低了15.7%和3.0%；翼缘受拉时的延性系数与现浇试件的相同，而翼缘受压时的延性系数则低于现浇试件的；两者刚度退化规律基本一致，叠合试件累积耗能明显低于现浇试件的；叠合试件腹板、翼缘板和T形后浇边缘部位的水平连接方式整体工作性能良好；根据试验结果，建议提高叠合试件构造边缘构件的体积配箍率。

Abstract: In order to study the aseismic performance of T-shaped assembled monolithic double-sided composite shear walls with constructional edge members, two full-scale T-shape shear wall specimens were tested. The test results showed that both the composite and cast-in-situ specimens displayed typical bending-shear failure characteristics in the axial compression ratio of 0.2. Compared with cast-in-situ specimens, the ultimate bearing capacity of flanges for composite specimens in the state of tension and compression was reduced by 15.7% and 3.0%; the ductility coefficient of flanges in the state of tension was the same as that of cast-in-situ specimens, while the ductility coefficient of flanges in the state of compression was lower than that of cast-in-situ specimens; the stiffness degradation laws of the two were basically the same. The cumulative energy consumption of composite specimens was significantly lower than that of cast-in-place specimens. The horizontal connection of webs, flanges and T-shaped constructional edges of composite specimens worked well as a whole. According to the test results, it was suggested to improve the stirrup ratio in constructional edge members of the composite specimens.
