摘要

结构动力特性是研究结构抗震等动力性能的基础

而正确地计算大跨径钢管混凝土拱桥这种新型结构的动力特性尤为重要.本文通过系统地总结钢管混凝土桥的地震响应分析理论

再以丫髻沙大桥作为研究对象

建立空间计算模型

确定地震波

利用ANSYS有限元分析功能

运用反应谱分析法和动态时程分析法

并分别考虑均匀地面运动和行波效应两种情况

进行丫髻沙大桥地震响应分析

并将计算结果与同济大学土木工程防灾国家重点实验室的计算结果进行了对比

得出相应结论.本文的结果为今后进一步研究钢管混凝土拱桥空间地震响应分析打下了良好的工作基础.

Abstract

The structural dynamical characteristic is the foundation to research the structural dynamical performance such as vibration-resistance

and it is greatly important to calculate correctly the structural dynamical characteristic of new structures for long-span concrete filled steel tubular arch bridges.In the paper

seismic analysis methods are summarized

and through establishing the spatial calculating model and seismic wave

utilizing ANSYS program

making use of response-spectrum methods and time-analysis methods

and considering ground movement and wave effects

the seismic response of Ya Ji Sha Bridge regarded as the research object is calculated.The result is compared with one carried out by Natural Lab Preventing Tragedy in Civil Engineering of Tongji University and some outcome is obtained.It provides a basic reference for the future research work for seismic ansysis of concrete filled steel tubular arch bridges.
