摘　　要：为了满足绿色农房产业化的需求,研发了一种装配式轻钢边框-单排配筋薄墙板组合结构受力体系.进行了轻钢框架及组合结构单元低周反复荷载试验,分析了再生混凝土的填充作用对轻钢框架的影响以及墙板钢筋暗支撑、墙板厚度与轻钢边框截面对组合结构力学性能的影响.结果表明:与空钢管框架相比,钢管内填充再生混凝土具有良好的力学性能;薄墙板与轻钢框架组合结构在受力过程中呈现出明显的2道抗震防线.建议采用Park-Ang损伤指数来确定该类装配式组合结构在不同受力阶段的损伤指数,为结构抗震设计提供参考.To meet the requirements of green housing industrialization,a fabricated composite structure of thin slab with lightweight steel frame and single-row reinforcement was developed.The lightweight steel frame and the prefabricated composite structure units were tested under low cyclic loadings.The influence of recycled concrete filling on the light steel frame and the effects of the oblique reinforced support,the thickness of the slab and the cross section of the light steel frame on the mechanical properties of the composite structure were analyzed.The results show that compared with the empty steel frame,the steel frame filled with recycled concrete has better mechanical property.The composite structure for the thin slab with the steel frame exhibits two seismic lines in the process of stress.The Park-Ang damage index is suggested to determine the damage index for the assembled structure in different damage stages,which can provide reference for aseismic design.
