In this paper, analytical and experimental investigations are conducted on the tensile elasto-plastic behavior of local connections in concrete filled circular steel tube (CFT) column to wide flange beam connection using external diaphragm. This paper proposes a new analytical method for predicting the load-displacement relation of such local connections. The method is developed by modeling a part of tube wall with external diaphragm as a grid beam with a tetra-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.
