Abstract

Abstract

Experimental study on the bending performance of pre-damaged reinforced concrete beams strengthened with bonding CFRP under air and seawater environment was carried out in this contribution.The influence of seawater on the damage mode,cracks development,strain development and bending capacity,and so on of the strengthened beams were measured.Based on the experimental results,it was found that the bending capacity and stiffness of the strengthened pre-damaged beams were improved effectively.And development of cracks was limited.Although their performances were decreased obviously with time prolonged under seawater environment,the effect of reinforcement was still reliable.Finally,it should be pointed out that during the test,strain of the concrete complied with the plane-section assumption.
