Abstract

Structural strengthening of flexural steel members with hoop (layers oriented perpendicular to the member) carbon fibre layers is perceived to be futile. Favourably, it now appears that thin-walled circular hollow section (CHS) members can be more effectively reinforced by hoop and longitudinal fibres to preclude the buckling of the steel skin. This work describes the results of an experimental study designed to consider the behaviour of thin-walled CHS steel beams reinforced by CRFP sheets under pure bending. The behaviour of CFRP-reinforced CHS beams affected by fibre orientation and number of fibre layers is examined. The study demonstrates that the local buckling strength and ductility of steel beams can be enhanced by applying CFRP sheets in both the hoop and longitudinal directions. It has been shown that the reinforcing effect of CFRP sheets increases for tubes with higher cross-sectional slenderness.
