Abstract:

通过8个不同再生粗骨料取代率、轴压比、体积配箍率下的型钢再生混凝土短柱的低周反复加载试验,观察其受力过程及破坏形态,分析了不同设计参数对短柱的荷载-位移滞回曲线、骨架曲线、承载能力、刚度退化、延性及耗能等力学性能的影响。试验结果表明:型钢再生混凝土短柱的主要破坏形态为剪切斜压破坏;试件荷载-位移滞回曲线基本呈梭形;试件达到峰值荷载后,承载力下降较快、变形小、延性较差;再生粗骨料取代率对试件承载力影响不大,延性耗能随着取代率增大而有所减低;随着轴压比的增大,试件承载力提高但延性耗能降低幅度大;随体积配箍率的增大,试件承载力及延性耗能均相应增大。除轴压比较小的短柱外,其余型钢再生混凝土短柱的延性系数均小于3,表明短柱抗震性能较差。因此,在实际工程中应采取相应的措施以改善短柱抗震性能。
