Evaluation of Dynamic Stability of KHSR Bridges Using Train/Track/Bridge Interaction Analysis Method

차량/궤도/교량 상호작용 해석법을 이용한 한국고속철도 교량의 동적안전성 평가

This paper represents the results carried out to determine the dynamic response characteristics of Korea High Speed Rail(KHSR) bridges. The responses of the KHSR bridges subjected to the moving train loading are obtained through the simplified method for the 2-dimensional train/track/bridge interaction analysis in which the eccentricity of axle loads and the effect of the torsional forces acting on the bridge are included for the more accurate train/track/bridge interaction analysis. The results of the analyses are compared with the field test data to verify the performance of the 2-dimensional train/track/bridge interaction analysis method.
