A steel moment frame beam intersects a hollow structural section steel column utilizing a full-depth web plate connection and continuity plates matching the 50 KSI flange thickness and width. Three seven-eighths inch diameter erection bolts secure the bent plate connection with one-inch returns, welded with five-sixteenths inch complete joint penetration welds typically. A stiffener plate matching the beam flange thickness and width is attached beneath the metal roof deck. Complete joint penetration welds connect the hollow structural section column to the continuity plates, while intersecting corner beams attach to the cap plate and continuity plates with matching welds.
