Assessment of the service lifetime of existing reinforced concrete bridges

In this paper the assessment of reliability profiles for reinforced concrete bridges exposed to chloride attack is discussed, Three stochastic models for chloride induced corrosion of reinforced concrete slabs are presented, The service lifetime of a reinforced concrete bridge is defined as initiation of corrosion of the reinforcement. On these::assumptions the stochastic service lifetime of an existing structure is estimated. An example on the assessment of the lifetime of an existing bridge including sensitivity analysis is included.
