This paper describes the load-carrying capacities and the inelastic behavior of the tube end-plate joints subjected to tension. The yield line theory is applied to obtain the collapse load for these joints. Seven tests are reported. The yield load, the maximum load, the deformation capacity and the strain concentration are examined. The effects of the thickness of the gusset plate and the end plate on these properties are discussed. The finite element analysis using program "NIKE3D" is also illustrated to study the inelastic behavior and the collapse mode. It is shown, in particular, that the collapse load gives a suitable prediction of the yield load.
