摘要
通过模型振动台试验研究了自锚式悬索桥的抗震性能。以一座自锚式悬索桥为原型,根据相似比设计模型并进行了振动台试验。对试验得到的动力特性、阻尼比及输入安评波的地震反应进行了分析,并用有限元的结果和试验结果进行了校核,总结了自锚式悬索桥的抗震性能,为今后相关的工程项目提供参考。
Seismic performance of self-anchored suspension bridge is researched by the experiment of shaking table model.A model of self-anchored suspension bridge designed by similar scale is tested on shaking table.The dynamic performance,damping ratio,seismic response of waves are analyzed and the results of experiment are verified by FEM.Seismic performance of self-anchored suspension bridge is summarized which would be helpful to future engineering projects.
