Considering the Effect of Holes Distances of Beam Flanges on Seismic Behavior of Drilled Flange (DF) Connections

Reduced beam section (RBS) connection has known as a qualified rigid connection regarding AISC(2010) with acceptable ductility for Special Moment Resisting Frames (SMRF). Beam to column welded Connection with radius cut on beam flange is categorized as RBS connection in AISC(2010) code. In order to...
