摘要
大跨度斜拉桥一般都是交通运输的枢纽工程,因此,对斜拉桥进行正确有效的抗震设计,有着非常重要的意义。本文以南京长江三桥为工程背景,运用谱分析方法,分析桥梁的受力情况,确定内力控制点的位置。
The long-span cable-stayed bridges are the most important transbay transit center. It is of great theoretical and practical significance to conduct comprehensive and systematic investigation on the earthquake-resistance of bridge. The spectrum analysis is done to estimate seismic response of the 3rd Nanjing Bridge. Anylysing the seismic response of this bridge,is to determine the control points of the internal force.
