Abstract     [Full Text]
    A great number of moment-resisting steel structures collapsed due to ductile crack initiation at welded beam-column connections, followed by explosive brittle fracture in the Kobe (Hyogoken-Nanbu) earthquake in 1995. A series of experimental and numerical studies on cracking behaviors of beam-column connections in steel bridge piers were carried out by the authors
 
Key Words
    ductile fracture; post weld treatment; burr grinding; R-finish; beam-column connection; steel bridge pier
