密肋复合墙结构采用预制装配式或现砌现浇方法建造时,其内部密肋复合墙与外部隐形框架之间可以采用三种连接构造形式。为研究不同连接构造形式对密肋复合墙体抗震性能的影响,对3片不同连接方式的1/2比例墙体试件进行低周反复荷载试验,总结了密肋复合墙体试件的破坏过程和破坏特点,分析3片墙体在承载力、滞回曲线、刚度、延性等方面的差异,并对其主要影响原因进行讨论。试验研究表明:当钢筋、混凝土及砌块用量基本相同时,三种不同连接构造形式墙体在破坏形态和延性方面差别不大,但其各自抗震性能并不相同,采用现砌现浇式制作的密肋复合墙抗剪承载力和刚度明显优于预制装配式。
When the multi-ribbed composite wall structure is constructed by prefabrication or in-situ pouring, three types of connection structures can be adopted between the internal multi-ribbed composite wall and the external invisible frame. In order to study the influence of different connection forms on the seismic performance of multi-ribbed composite wall, the low-cycle repeated load test was carried out on the half-wall specimens with three different connection ways, and the failure of the multi-ribbed composite wall was summarized Process and destruction characteristics of the three walls of the bearing capacity, hysteresis curve, stiffness, ductility and other differences, and to discuss the main reasons for the impact. Experimental studies show that when the amount of steel, concrete and block are basically the same, the three different connected structural forms of wall are not very different in failure mode and ductility, but their respective seismic performance is not the same. The shear-resistant capacity and stiffness of the multi-ribbed composite wall are obviously better than the prefabricated ones.
