About this detail

A Wx moment connection occurs at a steel column with continuity plates and shear plates. Steel beams frame into both sides of the column web, secured with bolted shear plates and complete joint penetration welds at the top and bottom flanges. Grade 50 continuity plates match the beam flange thickness, and a grade 50 cap plate is provided at the roof condition in lieu of standard continuity plates when applicable. Additional stiffener plates are added to each side if dimension X exceeds three inches. Weld termination plates, back-up bars, and run-off tabs may remain in place unless a flaw is identified by the special inspector, and complete joint penetration welds are acceptable in lieu of double-sided fillet welds.
