In this paper, Characteristics by the difference between the difference of the detail and the welding method of the beam-to-column connection in steel gymnasium were examined by the test, and compared. The specimen is five in all. It is the one that each welding method, the panel form, and the welding size were changed. The difference among the plasticity deformation ability, the transformation properties in the panel part, destructiveness, and strength was compared by these five specimen. Both the opening moment and closing moment went to the loading method in cyclic loading of two times by the displacement-controlled by the hydraulic jack. On any specimen from the test result, the power decrease of closing moment was more remarkable than that of opening moment. Ultimate strength of the specimen that a manual arc welding and the small welding size was almost equal to the calculation value. However, because it has been decided by rupture the weld, it does not necessarily have an enough plasticity deformation ability. Ultimate strength of other specimen was decided by local buckling of the flange. There is enough strength, and it has an enough plasticity deformation ability.
