THE TECHNOLOGY AND RESEARCH OF STEEL STRUCTURE STRENGTHENED WITH CFRP

Abstract

Abstract: Fatigue failure is a common failure mode of the steel structure engineering applications. Traditional reinforcement methods improve the fatigue life of components,but it will bring many new problems due to the damage of the original structure. CFRP has lightweight and high strength characteristics. Steel structure strengthened with CFRP has a nice fatigue property. In this paper,the CFRP reinforcing principle,CFRP strengthening methods and CFRP strengthening research at home and abroad were summarized,to help the application of CFRP strengthening in engineering.

Key words: fiber reinforced polymer, structure strengthening, fatigue performance, temperature
