【摘要】：试验研究了2种不同连接构造的装配式混凝土剪力墙抗震性能,第一种为钢筋浆锚搭接干式连接节点,第二种则在第一种基础上进行构造变化,边缘构件局部现浇,墙肢中部仍然采用钢筋浆锚搭接连接,形成干、湿混合连接节点.分别制作1片干式连接节点、1片混合连接节点足尺试件进行低周反复荷载加载试验,并与同条件现浇试件进行对比.试验结果表明,在承载力、刚度、位移延性及耗能能力等方面,2种装配式试件均与现浇试件相当,其抗震能力可认为与现浇等同.同时,混合连接节点试件虽在耗能方面稍优于干式连接节点试件,但优势并不明显,且考虑到其施工工艺复杂,现浇混凝土浇筑质量较难得到保障,易对节点抗震性能产生明显不良影响,故不建议采用.
[Abstract]:The aseismic behavior of two kinds of assembled concrete shear walls with different connections is studied. The first is reinforced mortar anchor lap joint, the second is structural change based on the first, and the edge member is partly cast-in-place. In the middle of the wall, reinforced concrete anchors are still used to form dry and wet connection joints. One piece of dry joint and one piece of full-scale specimen of mixed connection joint are respectively made to carry out low-cycle repeated load loading test. The results show that the load-carrying capacity, stiffness, displacement ductility and energy dissipation capacity of the two kinds of fabricated specimens are equal to those of cast-in-place specimens, and their seismic resistance can be regarded as the same as cast-in-place specimens. Although the energy consumption of the mixed connection joint specimen is slightly better than that of the dry connection joint specimen, the advantages are not obvious, and considering the complexity of the construction technology, the cast-in-place concrete pouring quality is difficult to be guaranteed. It is easy to have an obvious negative impact on the seismic performance of joints, so it is not recommended.
