Risk Based Decision Making for Bridge under Multi Hazard

Abstract:

Article Preview

The bridges are of much importance to the transportation network system, as they connect key highways at crucial nodes. This paper reviews and discussed risk-based methodologies to assess the risk acceptability and cost-effectiveness of protective measures for bridge under multiple manmade or natural hazards. Three risk acceptance criteria based on fatality risks, failure probabilities and net benefit assessment were described and discussed. The decision support framework accompanying these risk acceptance criteria considers hazard probabilities, value of human life, physical and indirect damages, risk reduction and protective measure costs were studied and an illustrative example was presented.
