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

초록

This paper represents the results carried out determmine the dynamic reponse characteristics of Korea High Speed Rail(KHSR) bridgea. The responses of the KHSR bridges subjected to the moving train loading are obtained through the simplified method for the 20dimentional train/track/bridge interaction analysis on which the eccentricity of axel 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 fiels test data to vetify the performance of the 2-dimensional train/track/bridge interaction analysis method.
