摘要：

This paper proposes a simple model of a load-displacement relation for predicting the local tensile elasto-plastic behavior of a concrete filled square steel tube column to steel beam moment connections using an external stiffener. This model is developed by superposing the load- deformation relations of a tube flange and web with external stiffener. The tube flange with external stiffener is modeled as a grid beam with a tetra-linear load-deformation relation, while the tube web with external stiffener is modeled as a tension member with a tetra-linear load-deformation relation. This research verifies the analytical model by comparison with experiment results. The analytical results agree approximately with the experimental results up to large deformations.
