About this detail

A wide flange steel beam features reinforced web penetrations for both circular and rectangular cutouts. The reinforcement consists of steel plates matching the web grade, with a minimum thickness of three-eighths of an inch typical, placed on both sides of the web. Five-sixteenth-inch fillet welds attach the reinforcing plates around the opening per the specified geometry. Edge distances and clearance zones from supports are dimensioned relative to the beam depth and opening dimensions, including minimum spacing requirements of d over six and d over three maximum unless noted otherwise. All cut edges are specified to be ground smooth.
