文摘

TRC can improve the fatigue life and delay the development of fatigue cracks of RC beams. The coupling action of the sustained load and chloride corrosion causes RC beams’ fatigue life to decrease significantly. The amplitude difference affects the fatigue life of TRC-strengthened beams. The mid-span deflection development of TRC-strengthened beams under fatigue test undergoes three stages. The corrosion fatigue weakens the bond performance between the TRC layer and old concrete.
