Cold-formed stainless steel tubular structural members experienced web crippling failure due to localize concentrated loads or reactions are investigated. A series of tests on Fibre-Reinforced Polymer (FRP) strengthening of cold-formed stainless steel tubular structural members subjected to End-Two-Flange loading condition is presented. The investigation mainly focused on the effects of different adhesive and FRP for the strengthening of tubular stainless steel sections against web crippling. The test specimens consisted of ferritic stainless steel square and rectangular hollow sections. Six different adhesives and FRPs were considered in this study. The properties of adhesive and FRP as well as the bonding between the FRP and stainless steel tube have significant influence on the effectiveness of the strengthening. Most of the strengthened specimens were failed by debonding of FRP plates to stainless steel tubes. Mainly four different failure modes were observed in the tests, namely the adhesion, cohesion, combination of adhesion and cohesion, and interlaminar failure of FRP plate. The failure loads, failure modes and the load-web deformation behaviour of the ferritic stainless steel sections are presented in this study. It was found that the web crippling capacity of ferritic stainless steel tubular sections may increase up to 51% due to the strengthening of FRP.
