About this detail

A structural steel beam-to-beam non-frame moment connection occurs at a continuous beam running over a column support. The assembly features a top plate sized per beam flange dimensions with a specified length of 1'-10", and a cap plate measuring 3/4" by the column flange width plus 1" by the column depth plus 1", secured with four 3/4" diameter bolts at the beam gage. A cantilever beam sits on top of the column, supported by partial height stiffener plates of 3/8" thickness on both sides that match the beam flange width and align with the column web. Additional offset plates function as shear plates where perpendicular beams occur per plan, utilizing quarter-inch fillet welds where specified. The top plate includes a designated no-weld zone over the transverse beam, and stiffener plates are provided per detail specifications.
