The Flexural Behaviour of Tubular Steel Member Strengthened With CFRP

Carbon Fibre Reinforced Polymer (FRP) has increasingly become an attractive option for retrofitting steel structures. This paper presents the result of recent study of retrofitting three tubular steel tubes. The tubular steel tubes were cut at the center to represent the loss of steel volume due to corrosion. It was then wrapped with two and four layers of CFRP respectively. The specimens were then tested in a four point loading system and compared to the control specimen. The results show an improved load carrying capacity of the strengthened tubular steel tubes with insignificant reduction of ductility.
