Abstract

In this paper, change of load carrying capacity of bridges with time was analyzed referring to the safety inspect data stored in the KISTEC. From this study, it was known that the capacity is rated differently by various parameters such as inspector's subjective. Accordingly, an improved method, in this paper, is suggested which can correct deviation due to several uncertainties involved in rating process. The suggested method can be utilized for efficient maintenance of bridges such as cycles and determination of priority of retrofit, and estimation of service life etc.

본 논문에서는 한국시설안전공단에서 수행한 정밀안전진단자료를 수집 분석하여 공용년수의 증가에 따른 내하력 변화 양상을 조사하였다. 연구결과, 공용내하율이 평가자의 주관 등 여러 가지 조건으로 공용기간에 따라 큰 편차를 보이는 것을 알 수 있었다. 따라서, 기존의 내하력 평가에 관한 다양한 문제점을 분석하여 편차를 보정할 수 있는 개선된 방안을 제시하였으며, 이 방법은 공용중인 교량의 보강 주기와 우선순위의 결정, 공용수명의 추정 등 효율적인 유지관리에 활용될 수 있을 것으로 기대된다.
