Abstract.Concrete bridge structures in coastal areas generally fail to meet design expectations due to frequent heavy loads and corrosive environments. In order to further promote carbon neutrality, it is urgent to improve the service life of concrete bridge structures. Due to the limited number of existing methods for calculating and predicting service life, they cannot meet the demand. Therefore, based on the existing durability evaluation methods for concrete structures, this article proposes a service life prediction method for reinforced concrete bridge structures under the comprehensive action of … Read more →
