A new plastic mechanism model is developed in this paper for T-joints in Rectangular Hollow Sections (RHS) under concentrated force. This model includes the plastic hinges in the web, the membrane force in the flange and the strain hardening of the material. It can predict the yield load, the post-yield response and the ultimate load of a T-joint under concentrated force. The model developed in this paper is compared with the CIDECT model, the Kato model and the modified Kato model. The yield load, the post-yield response and the ultimate load determined from the present model are compared with 6 T-joint tests performed by Zhao and Hancock (1991) and 20 T-joint tests performed by Kato and Nishiyama (1979). The ratio (β) of the T-Joints tested varied from 0.291 to 0.890.
