A Grade 50 continuity plate connects within a wide-flange steel column. Plate thickness 'tcp' matches the greater of the beam flange or stub flange plate thickness. The plate welds to the column web or flange using a D1.8 seismic weld sized at 'tcp/2' on both sides. A one-quarter inch fillet weld is provided at the connection, and the plate features a one-half inch minimum radius at the corners. The assembly maintains a 'k1' column minimum dimension and a 'k plus one and one-half inch' clearance requirement. The connection is designated as a typical D1.8 weld, with specific instructions for the free side only.
