Web penetration guidelines for a W18x35 steel beam, specifying penetration dimensions and vertical placement measured below the top of steel. Unmarked penetration locations default to the center of the beam web, while horizontal placement is determined by the floor or roof framing plan. Connections follow the standard beam web penetration schedule, using minimum bolt requirements from the shear tab connection table unless special connection details apply.
