Abstract
Structural deficiencies due to aging is a direct indication of the increase in susceptibility of the nations bridges to seismic damage and is a matter of prime concern today. Corrosion attacks on reinforcing steel is a major reasons behind the degradation mechanism that renders the bridge to be structurally deficient. The current study focuses on the development of corrosion models to evaluate the area loss of steel reinforcement over time in reinforced concrete columns. To represent the increase in the probability of damage of the components and the bridge system to seismic events, fragility curves are developed at various periods along the service life of the bridge.
