摘要
桥梁在运营过程中,经常发生桥面铺装层破坏、剥落造成桥面板刚度发生变化。该文以一钢桁架桥为研究对象,通过有限元模拟分析在桥面刚度发生变化时,桥梁结构在车辆荷载激励下的随机响应。分析结果可为桥梁结构在桥面板刚度设计和加固维修方面提供一些建议。
The bridge deck pavement often occur damage,spall in service period,which cause the bridge deck stiffness to change.In this paper,a steel truss bridge is taken as the research object and the random response of bridge under vehicle load is analyzed by finite element method.The analysis results can offer some suggestions for deck stiffness design and reinforcement repair.
