N2 - This paper presents a series of tests on strengthened ferritic stainless steel tubular members using externally bonded high modulus Carbon Fibre-Reinforced Polymer (CFRP) plate. The CFRP plate strengthening is only applied to a small localize region subjected to concentrated load. The tubular members of square and rectangular hollowsections subjected toweb cripplingwere tested. Theweb crippling testswere conducted under two loading conditions of End-Two-Flange (ETF) and End-One-Flange (EOF). The tests were performed on five different sizes of tubular sections.Tensile coupon testswere conducted to determine the material properties of the ferritic stainless steel specimens. Most of the strengthened specimens were failed by debonding of CFRP plate from the ferritic stainless steel tubes. Two different failure modes were observed in the tests of the strengthened specimens, namely the adhesion failure as well as the combination of adhesion and cohesion failure. The failure loads, failure modes and the load-web deformation behaviour of the ferritic stainless steel sections are also presented in this paper.
