Abstract
The paper investigates the effect of concrete grade and reinforcement corrosion on the flexural loading capacity of reinforced concrete (RC) beams by using the finite element method software Abaqus. The surveyed beams have dimensions of 150x200x2100 (mm), with the concrete grade of B20, B30, B45 and degree of reinforcement corrosion of 0%, 2%, 4%, 8%, 10% and 15%. The results show that, the current model is highly reliable as the differences of bearing capacity between the simulated model and experiment of control beam and corroded one is 1.2% and 0.6% respectively. The corrosion of reinforcing steel bars reduces both yield and ultimate strengths of RC beams. The compressive strength grade of concrete has a small effect while reinforcement corrosion shows the great influence on the flexural strength of RC beams.
