A Study on the Effects of a High-Speed Railway Bridge Vibration induced by Moving Train on the Adjacent Bridge

열차주행에 의한 고속철도 교량의 진동이 인접 교량에 미치는 영향에 관한 연구

A study on the effects of a high-speed railway bridge vibration induced by moving train on the nearby bridge is performed. Longitudinal and lateral accelerations of slabs and piers which are calculated from moving load analysis of a high-speed railway bridge can be used as input ground motions for the adjacent bridge. Dynamic responses of the adjacent bridge considering soil-structure interaction effects are analyzed by sub-structure method. Analysis procedure is made of free field analysis, calculation of impedance and effective input load and soil-structure system analysis.
