ABSTRACT
ABSTRACT: The purpose of the present study is to develop a realistic expert system which can estimate reasonably the safety and the service life of concrete bridge decks, based on the deterioration models that are derived from traffic loads and environmental effects. The deterioration models due to chloride ingress and carbonation are established. The damage models due to repetitive traffic loads considering dry and wet condition of deck slabs are proposed. These models are used to calculate the remaining life of bridge deck slabs. The prediction models for service life of deck slabs due to loading and environmental effects are developed. The models include flexure, shear, fatigue, corrosion, carbonation of deck slabs. The expert system for prediction of remaining service life is finally developed based on the theories established in this study.
