Abstract
Extensive research has been undertaken on strengthening concrete columns using FRP wraps. Recent research has extended this technique into strengthening steel tubular and concrete filled steel tubular columns. The behaviour of FRP confined concrete columns is now well understood and accurate models for both design and analysis are available. The only gap in knowledge is perhaps the lack of understanding of why the FRP failure strain in FRP wrapped columns is significantly lower than the ultimate tensile strain in a coupon test and its quantification. This paper presents a preliminary study tackling this problem.
