Abstract
This paper described the ultimate strength and deformation limit of welded T-joints in cold-formed square hollow sections. Previous studies showed that the T-joint has an obvious peak load. with the failure mode of chord-web buckling at a ratio of branch width to chord width ($\beta$) of above 0.8. Similar to a T-joint with chord-flange failure mode, the strength at a certain deformation limit can be regarded as the ultimate strength of a T-joint Based on the experimental results including tests done by Kato and Zhao, the deformation limit was proposed as 3%B for $10.7{\leq}2{\gamma}(B/T){\leq}42.3$ and $0.8{\leq}{\beta}{\leq}1.0$. The strength formula of CIDECT and those of other researchers were also compared with the test results. Finally, the strength formula based on the column buckling was proposed.
