摘要
以沅江矮塔斜拉桥为工程背景,利用有限元软件MIDAS/CIVIL建立了三维模型,对结构动力特性进行了计算分析,并基于时程的抗震分析方法对结构进行了地震响应分析,对今后类似桥型的地震分析具有一定的参考价值。
This paper takes the Yuanjiang low tower cable-stayed bridge as the engineering background, uses the finite element software MIDAS/ CIVIL to establish the three-dimensional model, calculates and analyzes the structure dynamic characteristics, seismic analysis method based on the schedule for structural seismic response analysis, the results for seismic analysis of similar bridge has a certain reference value.
