This paper describes structural behavior of concrete filled square tubular steel column to H-beam connection without diaphragm. Four beam to column subassemblage specimens were tested under horizontal reversal loadings and constant axial load on column. Width to thickness ratio and strength of steel tube were specified as test parameters. Load and local displacement relation in beam flange to column connections showed semi-rigid characteristics. This behavior of the connection were modeled to tri-linear curve by analytical approach and estimating test results. Strength of connection were predicted by the method based on the yield line theory assuming yield mechanism to beam flange connection. Local displacement were calculated using stiffness of column plate and plastic ductility ratio of rectangular section beam. The modeled curves were agreed with test results.
