About this detail

Steel joist girders bear on a hollow structural section steel column. The connection features a three-quarter-inch cap plate welded to the column top, with two three-quarter-inch diameter erection bolts per girder tightened snug. A seven-eighths-inch by two-foot-long knife plate extends upward to connect the top chords, with a one-inch by three-foot-long plate used at detail 203A. The knife plate height is half an inch less than the joist girder seat depth, and fillet welds secure the top chord to the knife plate. Stabilizer plates measuring three-quarters of an inch by six inches by six inches minimum are provided below, with the bottom chord left unwelded to the stabilizer plate. A tie plate measuring a quarter inch minimum by four inches by four inches is centered across the joint.
