In the 1995 Hyougoken-Nanbu earthquake, brittle fractures of beam-to-column joints were widely observed. One cause is stress concentration of the scallop part. In recent paper published, it has been reported that non-scallop method improves on deformation capacities more than conventional scallop method. However, it is difficult that welded beam-to-column joints on site make use of non-scallop method. This paper presents the results of full-scale tests of welded beams-to-column subassemblies three types of improved connection details: i.e., drilled flange method detail and joint method details and horizontal haunched detail. Based on the test results, effective drilled flange method and joint method are proposed to decrease stress concentration of the scallop part and increase deformation capacity and ultimate strength. But horizontal haunched beams do not increase deformation capacity. This is attributed to the fact that material of weld is deteriorated.
