摘　　要：在不同轴压比情况下,对两个全轻混凝土框架结构梁柱中间节点进行拟静力试验,分析不同轴压比对试件的滞回曲线、延性、刚度退化和骨架曲线等抗震性能的影响.研究表明,轻质节能框架结构的滞回曲线呈反S形,具有良好的延性;当达到最大荷载时,试件出现明显的刚度退化且延性较差;随着轴压比增大,试件刚度退化速度明显加快、延性性能逐渐降低、耗能能力显著增强.研究成果可为全轻混凝土在工程中的应用和推广提供参考.Under the condition of different axial compression ratio, the quasi - static test is carried out on the middle joint of the beam column of two full light concrete frame structures, analysis the effect of axial compression ratio on the hysteretie curve, ductility, stiffness degradation and the skeleton curves of seismic performance. The research shows that the hysteretic curve of the lightweight energy saving frame structure is anti S and has good ductility; When the maximum load is reached, the specimen has obvious stiffness degradation and the ductility is poor; With the increase of axial compression ratio, significantly enhance the stiffness degradation speed, ductility, energy dissipation capacity decreased gradually. The research results can provide reference for the application and popularization of the whole lightweight concrete in engineering.
