About this detail

A steel beam web opening detail featuring a circular cutout reinforced with a standard pipe matching the flange width, maintaining a minimum thickness of 0.375 inches with a snug fit and welded connection. Holes must not be field-cut in the web, must use the corresponding pipe section from the schedule, and cannot be located within 2 feet of any concentrated load. Concrete deck reinforcement includes number 4 bars at 12 inches each way, extending past the opening, alongside heading shear anchors spaced at 6 inches on center minimum over the opening and extending 3 feet 6 inches beyond the edge toward the center of the beam.
