Abstract

A number of research studies have shown that the axial load carrying capacity of reinforcedconcrete columns increases substantially when wrapped with FRP. In addition FRP wrappingalso increases the lateral deformation capacity of the columns especially under eccentric loads,thus suggesting that an introduced slenderness effect has to be considered when columns arewrappedwith FRP sheets. Six circular RC columns were cast and divided into two groups whichwere tested under 25mm and 50mm eccentricity. Both groups had an unwrapped column, athree layer FRPwrapped column in the hoop direction, and a column which had discrete verticalFRP strips attached to its surface before a three layer of FRP wrapping in the hoop direction. Thevertical FRP strips were observed to limit the introduced slenderness due to FRP wrapping inthe hoop direction for both eccentricities.
