하중 · 저항성분 변동계수에 따른 PSC-Box Girder 철도교의 신뢰도지수 민감도 분석

초록

As part of the development of the limit state railway bridge design code, it should be performed to estimate reliability indexes of existing railway bridges prior to setting up a proper target reliability index in order to introduce the reliability based limit state design method to design practice. In this paper, the sensitivity analysis for reliability index obtained from 40m-span simply supported PSC-Box girder railway bridge are performed and the results are analyzed about the impact of coefficient of variation.
