The authors have previously proposed a non-linear load deformation relation model for predicting the local elasto plastic behavior of internal-diaphragm-type and through-diaphragm-type connections between steel beams and concrete-filled square steel tubular columns. This method was developed by superposing the load-deformation relations of a tube and a diaphragm. The tube flange was modeled as a grid beam with a tetra-linear load-deformation relation, while the tube web and diaphragm were modeled as tensile members with a tri-linear load-deformation' relation. This research verifies the analytical model by comparison with experiment results of column-to-wide flange beam connections. The analytical results agree approximately with the experimental results up to a large deformation.
