Design of FRP strengthening in metal yield zones Available to Purchase

Both bond slip and rigid bond analyses of fibre-reinforced polymer (FRP)-plated metallic members are used to hint at recommendations for design of FRP flexural strengthening schemes in zones where the metal yields. The important role played by the stress history of the metal within these yield zones is highlighted. It is demonstrated that although the rigid bond assumption provides a convenient basis for design checks, this assumption can, in zones of metal yield, lead to dramatic over-estimation of the peak shear stresses in the bonding adhesive layer. The extent of this over-estimation is shown to vary with the form of the applied loading. The article ends with suggestions for further work.
