摘要
以连续梁桥汾江大桥为背景,利用ANSYS和MATLAB自编程序分析了车道位置、路面等级、车速等因素对桥梁动力响应的影响,并对桥面动力响应频谱特征进行分析,可为桥面加固及车桥耦合振动研究提供参考。
With the background of Fenjiang Bridge,ANSYS and MATLAB are used to investigated the vehicle-bridge interaction problem with different factors including lane position,road grade and vehicles speed.The spectrum characteristics of the dynamic response of the bridge are analyzed too.The results can provide a reference for the research of vehicle-bridge coupled vibration and bridge deck reinforcement.
