摘要
根据3个钢管再生混凝土压弯构件在水平低周反复荷载作用下的试验,考察了含钢率、轴压比两个参数变化对构件受力性能的影响,并对构件的滞回曲线、骨架曲线、刚度退化曲线进行了分析,研究构件的延性和耗能能力。研究结果表明,钢管再生混凝土试件含钢率越大,试件延性越好;轴压比越小,其延性越好。钢管再生混凝土柱在合理的含钢率和轴压比下有良好的承载能力、延性指标和耗能能力。
Based on the test of 3recycled aggregate concrete-filled steel tube bending members under horizontal low cyclic loading test,the change of two parameters,steel ratio and axial compression,affects the members on the stress performance,and the hysteretic curves,skeleton curves and stiffness degradation curves of the members are analyzed,the ductility and energy dissipation capacity of the members are studied.Research results show that the ductility of the specimens is proportional to the steel ratio,and also is inversely proportional to the axial compression ratio.Recycled aggregate concrete-filled steel tube columns have excellent ductility and energy dissipation capacity under rational steel ratio and axial compression ratio.
