Abstract

The town bridges are among the most important structural elements that decrease the traffic problems. The bridge management system is one of the significant components of the transport management system. Allocating appropriate funds for repairing and maintaining the bridges for the governmental institutions is needed. Therefore, in big cities with multiple bridges and limited funds, the need to investigate the bridges for their repair, maintenance, enforcement, resistant making, and substituting the risky ones increase. In this study, for the first time, through using two methods of decision making, the FUZZY aggregate simple weight (FSAW) and the analytical network procedure (ANP), the risk ability of various bridges in Babolsar in a case wise approach was appraised and it became evident that the second bridge of this city has a high risk compared to the other bridges of the city. Also, in this paper, for the first time, the risk appraisal of the bridges in the exploitation mode was investigated. Examining the effective measures on the risk of the bridge along with the findings of prior research showed that earthquake, flood, traffic load, bridge abrasion and the life span of the bridge are the most important measures of appraising the risk of bridges in the exploitation mode. The bridges in Babolsar were investigated through using the two methods of decision making, ANP and FSAW. It was found that the first bridge of this city has the most probability of destruction and should be given more attention.
