Cracked cross-beam connections made of thin-walled rectangular hollow sections (RHS) are repaired with carbon fibre reinforced polymer (CFRP) composites and constant amplitude fatigue experiments are conducted on the repaired specimens. In the previous pilot test on a T-connection of square hollow sections (SHS), early debonding happened in the corner region due to peeling effect. In this study, circumferential or transverse restraining CFRP patches are applied in the corner region which prevent early debonding and lead to significant increase in fatigue life. Furthermore, the addition of strengthening steel plates has further increased the flexural stiffness and fatigue life of the cracked specimens. © 2011 Tsinghua University Press, Beijing and Springer-Verlag Berlin Heidelberg.
