Economic Design of SMF Connection Continuity Plate Welds [O13]

For certain beam-column combinations in Special Moment Frame (SMF) design, the Seismic Provisions for Structural Steel Buildings (AISC 341-16) requires complete joint penetration groove welds (CJP) between continuity plates and column flanges, implicitly requiring that continuity plates need to remain essentially elastic. Recent experimental tests of two large-scale reduced beam section (RBS) SMF beam-column connections were comprised of details with fillet welds for connecting continuity plates to column flanges and column web.  This session presents a simplified design procedure for designing continuity plate fillet welds to column flanges and web, using a capacity-based approach.
