Abstract

Numerous moment connections of steel moment-resisting frames were damaged with brittle fracture during the 1994 Northridge earthquake. Since this earthquake, many studies were conducted to improve the seismic performance of moment connections. This study focuses on improving and enhancing the ductility of web-bolted flange-welded moment connections. By enlarging beam flanges at the beam-to-column joint, proposed widened beam flange connection is diminish potential for brittle fracture at the beam-to-column interface. Full-scale specimens were designed and experimented to clarify their seismic performance. Test results indicate that the connections, with widened beam flanges functioned as a reinforcement at the beam-to-column joint, are able to perform sufficient plastic deformation in the beam away from the column face, and develop reliable hysteresis performance with over 4% rad story drift angle.
