摘要: 以一座大跨高墩连续刚构桥为对象,采用纤维单元,建立该桥的动力分析模型,沿顺桥方向分别输入不同类型 场地上的实际地震动,计算其非线性时程响应。比较了场地条件对大跨高墩连续刚构桥地震响应的影响,指出了连 续刚构桥墩高差异较大时抗震设计中应注意的问题,并讨论了轴压比对桥墩滞回性能的影响。

Abstract: Taking a high-pier and long-span continuous rigid frame bridge as the research project,the dynamic time-history analysis model is established by using the fiber element. By inputting the actual seismic waves in longitudinal direction of different site conditions into the analysis model,their nonlinear time-history responses are analyzed respectively. Based on the analysis results,the effects of seismic response due to different site conditions are compared. And some problems needing attention in seismic design of continuous rigid bridge are pointed out. And the effect of axial compression ratio on hysteretic behavior of pier is also discussed.

Key words: continuous rigid frame bridge, seismic response, nonlinear, time-history analysis
