초록
현재의 교량유지관리시스템에서는 교량들의 사용수명 동안에 좀 더 객관적인 상태평가를 필요로 한다. 따라서, 본 연구에서는 이러한 점을 해결하기 위한 단면저항능력에 대한 정량적평가법이 개발되었다. 이 기법은 차량하중 및 염해나 중성화 같은 환경인자의 영향을 받는 콘크리트 교량의 손상 메카니즘에 기초를 두고 있다. 또한, 하중 및 극심한 환경조건하에 있는 슬래브 교량에 적용하였는데, 제안된 정량화 모델은 두 가지 인자를 잘 고려하여 교량의 열화를 잘 모사하였다.
Abstract
Bridge Management System (BMS) requires a more objective condition assessment over the lifespan of a given bridge. Thus, a quantitative assessment model of resistance capacity was developed here to meet the requirement for deteriorated concrete bridges. The model focuses on damage mechanisms of concrete bridges deteriorated by traffic loads and environment factors such as chloride and carbonation attacks. Also, it was applied to a typical concrete slab bridge which was severely damaged due to both load and environmental conditions. It was shown that the proposed quantitative model simulates well the deterioration level considering the two damage criteria.
