建立了 PC简支梁铁路桥制动力作用下线桥结构动力分析模型 ,在列车轮对制动力转换成结构节点制动力时程的基础上 ,用直接积分法对线桥结构进行了动力响应分析 ,并与实测结果进行了比较
The dynamic analysis model of the bridge under the braking force of PC simply supported beam railway bridge was established. Based on the analysis of the braking force of train wheel converted to the braking force time history of the structural node, the dynamic response of the bridge structure was analyzed by direct integral method , And compared with the measured results
