Abstract: Experimental investigations were carried out on corroded reinforced High Performance Concrete (HPC) beams of size 150 mm X 250 mm X 3000 mm under both static and cyclic loading, separately under four point bending. Some of the beams were provided with 10%corroded steel and some with 25%. Corrosion of reinforcement was induced by immersing the RC beams in Na Cl solution and by electrical conductivity and monitored with the corrosion analyser. The trend of the load-deflection relation of the beams was similar to that in the case of normal reinforced concrete beams under static loading. The strain energy absorbed by the both categories of the beams was calculated. It was found that the energy absorbed by corroded beams were lower by 10%, 25%, respectively. Some of the beams were also tested under cyclic load separately. It was observed that the deflection, compressive strain, tensile strain of the beams increase with the number of cycles. The paper presents in detail the experimental investigations conducted on beams and pertinent conclusions drawn there from.
