Abstract

In particular, the investigation of tendons in PSC Box Girder Bridge should be done in a systematic way. It is important to identify preventative maintenance activities that should be carried out in order to analyze the risk factors by type of representative tensions and to reduce risks in the long term. However, in the current maintenance system, various methodologies for investigating and repairing tensions have been studied, but it is difficult to investigate precisely tensions. Therefore, to apply the risk assessment for screening of tensions to the domestic PSC Box Bridge, we presented a risk matrix evaluation index that is consistent with the state assessment and maintenance system.

PSC 박스교에서 긴장재에 대한 조사는 체계적인 방법에 의해서 수행되어야 한다. 대표 긴장재 유형별로 위험 요인을 분석하고 장기적으로 위험도를 낮출 수 있도록 유지관리 계획이 수행되어야 할 예방적 유지관리 활동을 도출하는 것이 중요하다. 하지만 현 유지관리체계에서는 긴장재의 조사 및 보수보강을 위한 다양한 방법론이 연구되어 지고 있으나, 현실적으로 긴장재를 전수조사하는 것에는 어려움이 있다. 따라서 긴장재 선별에 대한 리스크 평가를 국내 PSC 박스교에 적용하기 위해 상태평가 및 유지관리체계에 맞춘 리스크 매트릭스 평가 지표를 제시하였다.
