About this detail

Continuity plates are welded to the structural steel column flanges aligned with the beam flanges, using a complete joint penetration groove weld with backing left in place and a five-sixteenths inch fillet weld underneath. All continuity plates are Grade 50 steel with a minimum thickness equal to the beam flange and three-quarters inch minimum. Where required, doubler plates are installed continuously through the connection with specific clearances and fillet welds per the structural notes. Weld tabs are removed to one-quarter inch maximum from the plate edge and weld ends are ground smooth without gouging the column flange. Welds at these locations are designated as demand critical per AWS D1.1.
