Study of the Structure Importance in Pipe Bridge Failure Fuzzy Assessment

Abstract:

The safety status of pipe bridge is often studied by fuzzy assessment. In fuzzy assessment, the structure importance must be calculated first. In this article, structure importance is calculated by Fault tree analysis(FTA) and Analytic hierarchy process(AHP). The result shows that the structure importance calculated by both methods is less than 30% different from each other. That means two methods are of high consistency and both is suitable for pipe bridge.
