Fatigue Behavior of Flexural Reinforced Concrete Beams under Corrosion Conditions

Abstract

The article is devoted to the fatigue of bending reinforced concrete beams under reinforcement corrosion. The influence of lugs and rebar notches periodic profile in concrete under repetitive loads, which act as stress concentrators, leading to the appearance of fatigue cracks and to the reduction of fatigue strength, is considered.
