In this paper, analytical and experimental investigations are conducted on the tensile elasto-plastic behavior of new vertical-stiffener-type local connections between steel beams and concrete-filled tubular steel columns. The beam-to-column connection requires no curvature to be formed for welding and shearing steel plates, and it simplifies the steelwork. This paper proposes a new analytical method for predicting the load-displacement relation of such local connections. This method is developed by superposing the load-displacement relations for a tube and a stiffener. The tube is modeled as a grid beam with a tetra-linear load-displacement relation, while the stiffener is modeled as tensile members with a tri-linear load-displacement relation. These analytical methods are found to agree with experimental results up to large deformations.
