钢箱系杆拱桥抗震性能分析
|
摘要
以某钢箱双曲拱桥为工程实例,通过建立有限元模型,分析了该桥的自振特性和地震作用下的反应。并以设计值作为参考标准,分析讨论了随着桩基长度和约束条件的变化,该桥自振特性和抗震性能的改变,研究发现桩长和约束条件都对桥梁的动力性能有较大的影响。研究结果可为钢箱系杆拱桥的合理抗震设计提供参考。
Through establishment of FE model this paper analyzes the seismic response and natural characteristics of a bridge in Fujian,which is a double curved arch bridge with steel box. Taking the design value as reference standard,the authors analyzed and discussed the change of natural vibration characteristics and seismic performance of the bridge,as the pile length and the constraint conditions change. The results show that both the length of pile and the constraints conditions have a significant impact on the dynamic performance of the bridge. This study can provide a reference to the reasonable seismic design of steel box tied arch bridge.
