Evaluation of Impact Factor of High-Speed Railway Bridges from Dynamic Response under KTX Running
고속철도교량의 동적응답에 의한 충격계수 평가
Abstract
To consider dynamic magnification effect at the static design stage, impact factor is applied to design load. Current impact factor adopted EUROCODE without domestic verification through theoretical and experimental studies. This study evaluated impact factor of railway bridges from dynamic response under KTX running. Moving Average Method was applied to calculate impact factor. Investigation considering different type of bridges and tracks including velocity was conducted.
