摘　　要：提出了一种轻型钢管混凝土芯柱-保温夹层砌体组合墙,为研究这种墙体的抗震性能,进行了3个不同构造组合砌体墙与1种带限位装置的玻璃珠-石墨基础滑移隔震技术结合的低周反复荷载试验,试件1为轻型钢管混凝土芯柱-再生砖组合墙试件,试件2为轻型钢管混凝土芯柱-粉煤灰砌块夹层-再生砖组合墙试件,试件3为轻型钢管混凝土芯柱-粉煤灰砌块夹层-端部再生砖约束型土坯组合墙试件,各试件墙体两端均内置了竖向构造钢筋。对比分析了各试件的破坏特征、承载力、延性和滞回性能,给出了轻钢芯柱-保温夹层砖砌体墙的承载力计算公式,计算结果与试验符合较好。研究表明:轻型钢管混凝土芯柱-保温夹层砌体墙具有良好的抗震性能,可用于农村低层房屋砌体结构抗震设计。A masonry composite structure with lightweight concrete filled steel tube core column and thermal-insula- tion sandwich is proposed in this paper. In order to research the seismic performance of the wall, the low-cycle loading experiments on three different composite walls combined with one kind of technology by sliding isolation with glass bead and graphite were designed. Specimen one was lightweight concrete filled steel tube core column-re- generation brick wall, specimen two was lightweight concrete filled steel tube core column-flyash blocks interlayer- regeneration brick wall, specimen three was hghtweight concrete filled steel tube core column-flyash blocks interlay- er-adobe wall with end region regeneration brick. The failure characteristics, bearing capacity, ductility and hyster- etic behavior were analyzed. In addition, the formula on crete filled steel tube core column and thermal insulation bearing capacity of the masonry wall with lightweight con- interline was obtained. Meanwhile, the calculated results coincide well with the experimental ones. The researches indicate that the masonry wall with lightweigh filled steel tube core column and thermal-insulation sandwich has good seismic performance and it can be the seismic design of low-rise masonry structure. t concrete applied to
