Fatigue Life Prediction of Corroded RC Beams Strengthened with CFRP under Repeated Loads

Abstract:

Structural deterioration is becoming a major problem when considering long-term performance of infrastructures. The actions of corrosive environment, repeated loading and concrete cracking lead to structural degradation, whereas externally bonded carbon fiber reinforced polymers (CFRP) may increases structural performance. In the present paper, a theoretical model based on fatigue performance of materials and stress analysis for cross-section is proposed in order to analyze the fatigue damage of corroded reinforced concrete beams strengthened with CFRP under repeated loads. Further, fatigue life is predicted by applying this method, and the method is evaluated by test results.
