構造ヘルスモニタリングと技術者判断を融合した意思決定枠組みの構築

抄録

This study aims to present a decision-making framework that combines structural health monitoring data with expert opinions. Monitoring data are used to estimate hidden state variables which are utilized for time-dependent reliability analysis to primarily judge the structural safety. If a probability of failure exceeds the target probability, experts are deployed onsite for a secondary judgement. Qualitative visual inspection is modeled by a binary decision. Life-cycle cost including risk is calculated as a preliminary investigation on quantifying cost-effectiveness of this framework. A long-term tension monitoring of a cable-stayed bridge is used as an exploratory study to show an applicability of the proposed framework.
