The Relationship

Based on the theory of vehicle-bridge coupled vibrations, the influence of transverse linear stiffness of double column piers on dynamic response of the train and bridge is investigated. A dynamic model of vehicle-bridge coupled system is established to analyze a high-speed railway bridge by BDAP software (Bridge Dynamic Analysis Program). By comparing the dynamic responses of piers which have different transverse linear stiffness, the characteristics of the relationship between the transverse linear stiffness of pier, the height of pier and transverse dynamic response are summarized, additionally some suggested values for transverse linear stiffness of piers are given to offer guidance for the design and construction of high-speed railway bridge.
