Abstract:为研究砌体类型对填充墙框架结构抗震性能影响,开展了4榀足尺填充墙框架与1榀空框架试件的水平低周往复荷载试验。填充墙砌块类型包括空心黏土砖、混凝土空心砌块、陶粒混凝土砌块和加气混凝土砌块4种。基于试验结果分析了不同砌块类型对填充墙框架破坏形态、滞回特性、骨架曲线、耗能性能、承载力和刚度退化等的影响。试验结果表明:加气混凝土砌块填充墙在整个加载过程中均表现出良好的整体性,而其他三种砌块填充墙在位移角1/50时即出现局部压溃剥落,并随位移角幅值增加破坏逐步加重;砌体填充墙的存在增强了填充墙框架的初始刚度和屈服割线刚度,同时也明显增大了其水平承载力;各填充墙框架试件的位移延性系数均大于5,其中加气混凝土砌块填充墙框架的承载力和刚度退化较慢,表现出比其他三种砌体填充墙框架更好的变形能力;基于试验结果并结合国内外框架抗震性能水平的划分标准,提出了砌体填充墙框架结构不同抗震性能水平的层间位移角限值。
