Determination of Remaining Service Life of Reinforced Concrete Bridge Structures in Corrosive Environments after Load Testing

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Reinforced concrete (RC) bridge structures deteriorate with time, and corrosion of reinforcing steel is one of the main causes for that. Load testing alone is unable to provide information about the extent of deterioration and remaining service life of a structure. In this chapter, a framework for the reliability-based assessment of the remaining service life of RC bridge structures in corrosive environments will be described. Existing models for corrosion initiation, corrosion-induced cracking, and effects of corrosion on stiffness and strength of RC members will be considered. Special attention will be paid to the potential effects of a changing climate on corrosion initiation and propagation in these structures. Examples illustrating the framework application will be provided.
