Abstract
In bridge risk assessment, it is necessary to assess the probability and severity of the hazard, and the risk quality can be considered as a combination of the probability and severity of the hazard. Objective of this thesis finding the best location Bridge Risk Assessment USING Grey Relational Analysis (GRA). GRA method, incompletely known weight Many are intuitively confused with information For Solving attribute decision-making problems Calculation steps are given. Solution and negative-optimal solution between each alternate and positive-best the size of the gray relation is calculated. then, Positive-best solution (BIS) and negative-best The solution (NIS) is the same for calculating both amount of gray relation in time Rank A relative correlation The order of all alternatives to be decided is defined by degree. Finally, grown up Check the approach it’s practical and Assessment Medium high (MH) is got the first rank whereas is the Low is having the lowest rank.
