摘要
为了解RC-加气混凝土砌块组合墙的抗震性能,进行3片不同构造形式的RC-加气混凝土砌块墙的水平低周反复荷载试验。介绍组合墙试件的破坏过程和破坏特点,重点研究3片试件的承载力、滞回曲线、刚度和延性性能,并与已有普通加气混凝土砌块墙试验数据进行对比分析。研究结果表明:构造柱和系梁限制砌块裂缝的产生和发展,改善砌块的脆性性质,提高砌块的力学性能;通过合理构造措施将钢筋混凝土与加气混凝土砌块结合在一起形成的组合承重墙,具有较好的抗震性能,为加气混凝土砌块墙在多层房屋结构中的应用提供基础。
Three composite wall specimens of RC-autoclaved aerated concrete blocks were tested under cyclic lateral loading to investigate their seismic performance. The damage processes and failure characters of the composite wall specimens were presented. And the load-bearing capacity, hysteresis behavior, stiffness and ductility capacity of the composite wall specimens were investigated, which were compared with those of the ordinary wall of autoclaved aerated concrete blocks. Test results show that the presence of constructional columns and beams constrained the propagation of cracks in the autoclaved aerate concrete blocks. And then the brittle behavior of the autoclaved aerated concrete blocks is changed, and the mechanical performance of the autoclaved aerated concrete blocks is improved. Composite wails of RC-autoclaved aerated concrete blocks with reasonable forms possess good seismic performance, and research on the composite walls provides a basis for the application of walls of autoclaved aerated concrete blocks in multi-storey buildings.
