Abstract

This paper presents a design method of predicting the strength of steel circular hollow sections, externally reinforced with carbon FRP sheets in bending. The aim of this study is to examine the applicability of strengthening parameters in current design equations, notably the Australian Standards (AS 4600 &AS/NZS 4100) and the European Standard EC 3.A method for generating bending strength curves for the Australian and European standards is described herein. The strengthened tube is analysed based on the concept of modular ratio and by incorporating the limiting slenderness ratios. The influence of the amount of CFRP, modulus of elasticity of the hoop CFRP and steel yield stress relative to the strength of a CFRP sheet strengthened steel tubular beam is taken into account. The strength curves give a quantitative indication of the strengthening effect due to the externally bonded composite system.
