ABSTRACT
Corrosion in reinforcement is one of the major problems in the durability of any types of reinforced concrete structures exposed to aggressive environment. Deterioration caused by corrosion reduces the durability and the safety margin of concrete structures to an extent of serious structural failure, causing huge amount of costs in managing these structures. This paper aims to investigate the effects of the reinforcement corrosion on the residual strength of corrosion damaged reinforced concrete structures exposed in aggressive environment. A new analytical method has been proposed to evaluate the residual strength of concrete structures with corroded reinforcement failing in bond. The results from the analytical predictions show that the proposed approach is capable of predicting the residual strength of corrosion damaged concrete structures. A sensitivity analysis has also been carried out considering three important factors: geometrical, mechanical properties of the concrete and type of the corrosion product. The study concludes that residual load carrying capacity of corroded concrete structures decrease significantly due to bond strength loss.
