- Structural Beams
- Confirm location and configuration of supplemental beams on floor- and ceiling joist plans
- All solid-sawn beams must be grade #2 lumber
- All solid-sawn beams must be glued and nailed
- Any solid-sawn beam having 3 or more members must be glued, nailed and bolted at 2-foot on center staggered. No portion of any bolt hole can be nearer than 2″ (top or bottom) to the edge of the beam.
- Check there is a double solid-sawn or engineered beam under all second-floor walls.
- Note: Bearing walls supported by floor joists or beams may be offset laterally from the bearing support below a distance equal to the depth of the joist
- Note: Double joists may be separated to permit installation of piping or vents, as long as full-depth solid blocking is fastened between members every 4 feet.
- Ensure multiple studs are installed under all beams and matching the width of the beams.
- Make sure any modifications to engineered beams (i.e., taper cuts, end notches, midspan notches, or bored holes) are in accordance with the limits specified in the manufacturers installation guide. Each beam manufacturer has different criteria.
- Note: Proper bearing length for an engineered beam, while never less than 1 1/2″, may exceed the 3 1/2″ width of a 2×4 topplate. Reference the manufacturers installation guide for required end bearing.
- When a engineered beam headers into a second engineered beam, ensure a rated beam hanger is used for the connection. Do not rely on end-nailing, a site-built or modified hanger, or lag screws.
- Flitch beams will be constructed in accordance with specifications from the Typical Detail Sheet
- Ensure beams, joists, and strongbacks do not stick up or protrude through the plane of the roof.
