About this detail

This structural steel detail establishes geometric parameters for a welded unreinforced flange welded web moment connection, featuring a beam framing into a column with dimensional criteria for the shear plate and weld access holes. Shear plate overlap with the weld access hole is dimensioned between one-quarter and one-half inch, with a one-inch minimum setback from the column face. The shear plate extends a minimum of two inches beyond the end of the weld access hole, while the distance from the end of the shear plate fillet weld to the edge of the access hole ranges from one-half to one inch. Weld access hole geometry angles are constrained between twenty and forty degrees. Beam and column sizes are sized per plan, with top and bottom flange moment connections detailed with weld access holes.
