Analytical investigations are conducted on the tensile elasto-plastic behavior of local connections in concrete filled square steel tube (CFT) column to steel beam connection using external diaphragm. This paper proposes a new analytical model for predicting the load-displacement relation of such local connections. This model is developed by superposing the load-deformation relations of a tube flange and web. The tube flange is modeled as a grid beam with a tetra-linear load-deformation relation, while the tube web is modeled as tensile members with a tri-linear. The strength of external diaphragm is superposed to strength of these tube load-deformation models. The analytical results agree approximately with the experimental results up to a large deformation.
