The increasing stock of short and medium span bridges in this region and around the world induces substantial maintenance and rehabilitation costs which result in a significant increase in financial burden to the government and industry.To relieve the long term financial pressure,a whole life cycle cost management concept was introduced in recent decades and is now getting more and more important in engineering design,construction and management.In the whole life cycle cost management model,the mechanism and prediction of structural member deterioration is essential.Among typical short and medium span bridges,such as steel-concrete composite structures,corrosion deterioration and fatigue damages are the most common types of degradation mechanism which are influenced by the environmental conditions,the vehicle loadings and its stress ranges.This paper focuses on the technical review on the typical structural deterioration,such as corrosion and fatigue,on steel bridge girders as well as concrete decks.To meet this challenge,this paper has developed several performance-based life-cycle management models for reinforced concrete decks and steel girders.These models are characterized in three aspects: (1) The corrosion and fatigue induced deterioration mechanisms are used to predict the service life of concrete decks and steel girders; (2) the performance of the bridge structure is measured by the condition index; (3) the performance limit states are mapped with condition index and field inspection data to come up with maintenance and renovation strategies.Thorough discussions on the application of the life cycle cost management concept in dealing with maintenance and rehabilitation of such bridges are illustrated with examples.
