Maximum web penetration sizes are limited to one-third of the beam depth, positioned within the middle third allowable zone of the web. Round and rectangular penetrations require a minimum spacing of two diameters for diameters under three inches, with a one-inch typical corner radius on rectangular cutouts. An intersecting framing member is shown connected via a bolted shear tab on the beam web.
