Brittle fractures in beam-to-column connections of steel buildings were widely observed under Northridge earthquake and Hyogoken-Nanbu earthquake. Many studies after these earthquakes have revealed that the brittle fracture is complexly affected by various factors. The purpose of the present study is to investigate influence of connection detail and material properties upon the brittle fracture. In order to estimate maximum strength and plastic deformation capacity of the connection, loading tests using subassemblage specimens and numerical analysis are performed. In this study, performance of the connection is discussed mainly in the following subjects: influence of connection detail and yield ratio upon strain distribution, and correlation between fracture toughness and initial fracture.
