International Beams now has an APA “Green Verification” report, GR-L252, which includes a checklist of approved points for IB I-joists using the LEED and ICC 700 green building programs.

Technical Bulletin (TB-IJ-10) Connection of Exterior Deck to IB I-Joist
Beginning in the 2009 edition of IRC (International Residential Code), there is a tension-tie requirement to meet prescriptive DCA 6-09 deck installation requirements for residential exterior decks. International Beams has released a new Technical Bulletin (TB-IJ-10) that provides guidelines on how to make this tension-tie connection to a floor system comprised of IB (International Beams) I-joists.

Architects, builders and design engineers can now get immediate access to International Beams updated I-Joist Floor Framing Details.
International Beams is pleased to announce that new framing details covering 20 specific framing situations are available as DWG, DXF and PDF files. To simplify the selection process, one can download either an individual DWG, DXF or PDF or a zip file containing a complete set of detailed drawings. There are separate files for the United States and Canada.
These details have been re-drafted and enhanced with additional information specific to IB.

Technical Bulletin (TB-IJ-9), Adding web filler for 2-ply (double member) IB I-joists with 2×4 flanges
When adding web filler for 2-ply (double member) IB I-joists with 2×4 flanges, it can be less labor-intensive to use dimensional lumber rather than cut structural wood panel to depth. The new TB-IJ-9 provides an alternate to the structural wood panel filler indicated in the IB literature.

International Beams LVL (laminated veneer lumber) typically comes in 1 ¾” thicknesses and is suitable for use as ledgers to support floor (or roof) framing. For example, IB LVL may be used to support an intermediate floor at balloon-framed walls, or it may be used to support floor framing when poured concrete foundation walls extend above the floor level.

There are situations where architectural geometric restrictions of the cornice detailing require that the attic ceiling/floor joist be cut at a slope to match the sloped rafters. The bearing and shear capacity can be seriously compromised with this type of sloped-end cut on an I-Joist. International Beams has tested sloped-end cuts on IB I-joists. As a result of these APA-witnessed tests, we have established maximum end reactions for unreinforced and reinforced sloped-end cuts.

Technical bulletin IB-LVL-2, Multi-ply IB LVL Fastening, has now been updated to include design tables for ½” diameter thru-bolts and Simpson SDW screws in addition to the previous table for TrussLok screws.
