力比对钢-混凝土连续组合梁抗震性能的影响
Effect of Force Ratio on Seismic Behavior of Steel-composite Continuous Beams under Low-reversed Cyclic Loading
【摘要】 本文介绍了5根不同力比钢-混凝土连续组合梁在竖向低周反复荷载作用下的试验结果,对其破坏形态、滞回曲线、骨架曲线、刚度退化规律、耗能能力、变形恢复能力等抗震性能进行了分析,结果表明综合力比对连续组合梁抗震性能有较大的影响。
【Abstract】 In this paper,the results of experiment on 5 steel-composite continuous beams which have different synthesis force ratio under low-reversed cyclic loading are introduced,and the seismic behaviors which involve failure pattern,hysteresis curves,skeleton curves,rigidity degeneration,energy dissipation and deformation-restoring behavior are analyzed.And the results show that the synthesis force ratio has great influence on the seismic behavior of composite continuous beams.
