Abstract

In coastal environment reinforcement corrosion is an obvious cause of deterioration of concrete structures, affecting strength and durability. The present study is an attempt to quantify the effect of reinforcement corrosion on the flexural strength of reinforced concrete beams. Experimental studies as well as numerical simulation have been performed. Since corrosion takes place over a considerable length of time, to achieve corrosion quickly, accelerated corrosion technique was adopted. Corrosion was measured using Applied Corrosion Monitoring (ACM) instrument. Corroded beams were tested in laboratory to evaluate their flexural behavior.In the numerical study, Finite Element method was used. Comparative studies were done for different levels of corrosion. Results show that as rate of corrosion increases, the deflection also increases but load carrying capacity of the beams reduces. It is observed that the stiffness of the beams is reduced nonlinearly when rate of corrosion is increased. The numerical modeling results are in conformity with experimental values and it is concluded that numerical modeling can be applied satisfactorily to measure load, deflection and to predict crack patterns.
