摘要

摘要: 为研究型钢再生混凝土结构(SRRC)的抗侧力性能,进行了3榀不同填充程度的型钢再生混凝土框架-再生混凝土空心砌块墙体混合结构的低周反复荷载试验。通过测试试件在侧向力作用下的受力过程和破坏形态,研究型钢再生混凝土框架结构的受力机理和抗震性能,获得了再生混凝土空心砌块墙体对框架的承载力和抗侧刚度的影响;分析结构在不同受力阶段的承载力和刚度变化情况,以及结构在同级循环荷载作用下的刚度退化规律。结果表明：型钢再生混凝土框架-再生混凝土空心砌块填充墙结构具有较高的承载力和抗侧刚度,全高填充墙对型钢再生混凝土框架抗侧刚度的影响较大,结构初始刚度大,而刚度衰减快,半高填充墙在结构受力初期可提高结构承载力和刚度,而在受力后期具有与空框架相似的退化规律。

Abstract: In order to study the lateral resistance of shaped steel-recycled concrete structures, low-cyclic reversed loading tests were carried out on 3 models of a shaped steel recycled concrete- recycled concrete hollow block wall hybrid structure. Based on the loading process and failure pattern of the specimens, the mechanical performance and seismic behavior of the shaped steel recycled concrete columns-reinforced recycled concrete beam structure were studied, and the influence of the recycled concrete hollow block wall on the bearing capacity and lateral stiffness of the frame was obtained. The changes in bearing capacity and stiffness of the structure under different loading phases and the rules governing structural stiffness degradation under circulating load at one level was analyzed. It was found that shaped steel recycled concrete frames with recycled concrete hollow block wall structure has high bearing capacity and lateral stiffness. A full-height wall has a great influence on the lateral stiffness. It has high initial stiffness, however that stiffness decreases rapidly. With a half-height wall, the structure has increased bearing capacity and stiffness at the initial loading stage, but displays degradation of bearing capacity and lateral stiffness similar to the bare frame’s.
