Abstract
Wang, L.; Li, C., and Yi, J., 2015. An experiment study on behavior of corrosion RC beams with different concrete strength.The flexural behavior of the corroded reinforced concrete (RC) beam with different concrete strengths under fatigue loading has not been truly well-understood. Twelve RC beams (section size 120×200; total length 1700 mm; clear span 1500 mm) with concrete strengths (C20, C25, C30, and C35) were tested under specified fatigue and monotonic load in this study. The tests were aimed to evaluate the mechanical behavior of the corroded reinforced concrete beams with different failure patterns after fatigue and monotonic loading. The parameters evaluated in this experimental study include distortion, stress distribution and ultimate strength of the corroded reinforced concrete beams. The results showed that the load capacity and the rigidity of the corroded beams are increased with the concrete strength. The performance of the RC beams is greatly affected by the corrosion in terms of fatigue capacity, which reduces the ultimate strength and the ductility of the beams significantly.
