About this detail

A structural steel moment connection between a steel beam and a braced frame column uses complete joint penetration groove welds at the top and bottom flanges. The shear tab is sized to match the thickness of the beam web minus one sixteenth of an inch and utilizes three seven-eighths-inch diameter erection bolts. Continuity plates matching the beam thickness are welded at the top and bottom inside the column. Weld access holes are detailed at the top and bottom of the beam web. The construction sequence specifies tightening erection bolts snug, welding the top and bottom flanges with demand critical welds, and finally welding the beam web.
