Abstract

Abstract: The dynamic behavior of long-span cable-stayed bridges subjected to seismic excitations is systematically investigated, based on a case study for Wuhan White Shoal Cable-stayed Bridge over Yangtse River, with particular emphasis on the effects of different longitudinal restraint conditions in main girder on the seismic performance of this bridge.Finally, several conclusions are drawn from the above study.

Key words: cable-stayed bridge, seismic response, restraint conditions, damper cable

摘要： 以武汉白沙洲长江大桥这座主跨618 m斜拉桥为例,研究了大跨度斜拉桥这种长大柔性结构物在地震作用下的动力行为,侧重于讨论不同主梁纵向约束方式对斜拉桥地震响应的影响,得出了一些有益的结论.
