Effect of post weld treatment on cracking behaviors of beam-column connections in steel bridge piers
Liang-Jiu Jia, Hanbin Ge and Toshimitsu Suzuki
Abstract
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
