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。
In this paper, the results of experiment on 5 steel-composite continuous beams which have different synthesis force ratio under lowreversed 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.
