To reduce fabrication time and labor, the authors developed a concrete-filled square tube column to a steel-beam connection reinforced by cast steel parts. The connections join a column with a beam using cast steel parts that have a function of nuts, split-tees and high strength bolts. To understand the elasto-plastic behavior of the joint panel of the connection, specimens modelling of the joint panel in shear were tested. The test results are summarized as follows; in the connection, the portion connecting upper or lower flanges of beam turned out to be a rigid zone because of the cast steel parts, therefore only the portion between the rigid zones was deformed. The smaller the width-thickness ratio of the square tube column or the ratio of height to width of the panel zone was, the greater the shear strength of the infilled-concrete was. Furthermore, the test result of load-displacement relationship can be approximated by the analysis assuming a tri-linear shear stress-strain relationship for the square tube column and the infilled-concrete.
