摘要
文章以某大跨度悬索桥为工程背景,分析了悬索桥结构的动力特性,同时采用反应谱和线性时程分析法对悬索桥在纵桥向、横桥向和竖向地震动作用下的地震反应特点进行探讨,为大跨度悬索桥的抗震设计提供参考。
With a large-span suspension bridge as engineering background,the article analyzed the dynamic characteristics of suspension bddge, at the same time the response spectrum and linear time history analysis method were used to explore the seismic response characteristics of suspension bridge under the impact of longitudinal, lateral and vertical excitation,thereby providing the reference for the seismic design of large-span suspension bridges.
