Ranking repair and maintenance projects of large bridges in Kurdestan province using fuzzy TOPSIS method

In this paper multi criteria decision making tools have been used for bridge risk assessment and for planning the investigation, repair and maintenance of bridges. For this purpose, at first, risks that influence bridges have been recognized and they have been classified in six groups as risks arising from earthquake and their effect on the sphere, design and traffic insufficiency, flood, structural system, structural resistance against earthquake and different design, building or maintenance problems. The risks have been assessed based on their consequence on four criteria as safety, functionality, cost and environment. Finally, a method has been proposed for planning the bridges repair and maintenance projects using multi criteria decision making tools. In a case study, large bridges in kurdestan province have been ranked based on the intensity of recognized risks using fuzzy TOPSIS method. [Heresh SoltanPanah Hiwa Farughi, Seiran Heshami.
