斜拉-连续刚构组合梁桥车-桥耦合动力响应分析
The vehicle-bridge coupling dynamic analysis of cable-stayed and continuous rigid-frame composite beam bridge
摘要
Abstract
Taking a cable-stayed and continuous rigid-frame composite bridge as an example,the vehicle-bridge coupling dynamic analysis model between train and bridge was built and then the spatial vibration equations in matrix form of the system were derived,based on the variational principle of the stationary potential energy and the set-in-right position rule of forming structural matrices.Based on the train runability evaluation,the spatial vibration responses were calculated when the domestic CRH2 train run through the composite bridge at different speeds in order to test whether the bridge has sufficient lateral and vertical rigidity and good operation stability of dynamic characteristics,etc.,meanwhile,the change rule of bridge response at different speeds was studied.The results can provide a reference to correlated bridges for evaluation and analysis.关键词
