Abstract

Abstract

This paper presents the results of experimental mechanical properties of metal pipeline strengthened by fiber reinforced polymers subjected to hydrostatic pressure.These metal pipelines were wrapped with different layers of CFRP sheets.The results show that the thicker layers of CFRP sheets, the higher the pressure bearing capacity.According to experimental results and thin-walled mechanics theory, the design equation of FRP thickness were set up when the metal pipeline was under elastic or plastic state.Based on the plasticity solution of thick wall cylinder in the polar coordinates, strength checking equation of strengthening structures was presented by different mechanical states.These design equations without iterative calculation are close to the experimental results and can be conveniently applied for actual projects.
