Title: The impact of corrosion on the mechanical behavior of welded splices of reinforcing steel S400 and B500 c
Keywords: Reinforced Concrete | Steel Corrosion | Performance Bonds

Abstract: The reinforcing steel, used in concrete structures, when corroded causes reduction of the strength properties and especially drastic reduction of ductility. Steel corrosion constitutes an important factor of progressive devaluation of its mechanical properties and serious reduction of the integrity of structures. The problem becomes more evident specifically for structures near coastal areas where salt corrosion is predominant. Reinforced concrete columns and beams are quite often extended by welding new steel reinforcement to the already corroded existing steel. In the present article the impact of corrosion on the mechanical properties of welded splices of reinforcing Steel S400 and B500 c is examined. An experimental investigation was conducted and tensile and compressive results are presented for welded precorroded S400 and noncorroded B500 c steel splices. The mechanical behavior of welded splices in tension are different in compression and depend strongly on the level of corrosi
