- Abstract
- Cross-beam connections are widely used in welded thin-walled structures made of rectangular or square hollow sections mainly due to the connection's requiring less welding and no member cutting. Re-welding or bolted splicing are not suitable for repairing or strengthening fatigue cracked cross-beam connections. In this research, a new method using Carbon Fibre Reinforced Polymer composites (CFRPs) is proposed. Repair/strengthening are conducted for thin-walled RHS cross-beam connections at different levels of fatigue damage before constant amplitude fatigue experiments are conducted again on the specimens. Fatigue test results of unstrengthened intact connections are also presented for the purpose of comparison. The results show that the proposed retrofitting method is effective in repairing/strengthening fatigue-damaged thin-walled cross-beam connections when the connections are not severely cracked.
