In this paper a concept for a method that can be used to assess the risk assessment of bridge is presented. The presented method can be taken into consideration major loading status, such as displacement, deformation and crack. In order to combine quantitative factor assessment, fuzzy synthetic assessment method based on analytic hierarchy process is used to evaluate bridge safety, in which experience of experts can be used sufficiently. The three general steps used to estimate bridge risk are, 1)index system of fuzzy synthetic assessment, 2)Fuzzy comprehensive assessment and 3)risk response. Based on matlab platform, bridge risk assessment system is developed. The system could produce the result automatically, when mathematical model is definition. Its function is concentrated on simulation analysis, which can deal with the quantitative and semi-quantitative risk assessment according to the engineering practice. The system has been used in many projects with a good result. |
