| 摘 要： | 多跨连续梁桥纵向延伸长度比较长,进行地震反应分析时应考虑地震波有限波速传播所引起的行波效应.以某长江大桥南引桥为例,推导了行波输入时结构的运动方程,并对其进行行波激励下地震反应的数值模拟,将结果与一致激励的结果比较,分析行波效应对于此类桥梁影响的规律性以及影响行波效应的因素.

| Abstract: | Multi-span continuous bridges have large extended length longitudinally,the more rational method for seismic response analysis should be performed considering the traveling wave effect.In this paper,The south approach of a Changjiang Bridge is taken as an example,and the dynamic equation of the structure considering traveling wave effect is calculated,the seismic responses of it are numerically simulated considering traveling wave effect and compared with the result under the coincident earthquake excitation in order to get the rule of such affection and the factor working on the traveling wave effect. |
