HomeMy WebLinkAboutTruss Joist Report TECHNICAL BULLETIN TB-818 July 2021 (Expires 7/2023) Page 1 of 10 1.888.453.8358 ● www.weyerhaeuser.com/woodproducts TJI® Joists with a Side Flange Notch in the Top (Compression) Flange The flange of a TJI® joist should never be deliberately cut or notched and TJI® joists subject to damage prior to installation should be discarded and replaced. However, it is recognized that an inadvertent notch to the flange of a TJI® joist may occur during the construction process, after the member has been installed. This technical bulletin provides contingency guidelines for TJI® joists with one (1) inadvertent Side Flange Notch in the top (compression) flange. Definitions • Side Flange Notch – notch type that encompasses the full flange depth and up to half the flange width Figure 1: Diagram of an inadvertent Side Flange Notch in top (compression) flange of a TJI® joist. Conditions and Limitations • Span tables are valid for flange notch contingency only. • Original, undamaged TJI® joists are properly designed. • Adjacent TJI® joists on both sides remain undamaged. • Uniform distributed loads only. • One (1) inadvertent Side Flange Notch per TJI® joist (single-ply joist members only). • Side Flange Notch permitted in location zones of top (compression) flange (see Figure 4 and Figure 5). • Notch depth (𝑑𝑛𝑛𝑡𝑐�) ≤ half the flange width (𝑏𝑓). • Length (parallel to span) of Side Flange Notch ≤ 4″. • Centerline of Side Flange Notch ≥ 6″ from nearest edge of rectangular or slotted holes. • Side Flange Notch due to saw-cuts or drilling only. - Excludes flange damage due to rough handling, drops, forklift stabs, etc. • Joist member slope ≤ 0.25/12. Should your situation conflict with any of the conditions and limitations, please consider an alternative option: 1. “Header-Off” the damaged TJI® joist around the location of the notch. - Reference Weyerhaeuser Engineered Wood Products Header-Off Span Table (TB-319). 2. Remove/replace the damaged TJI® joist or install an additional matched, undamaged TJI® joist within 3″ on-center of the damaged member. - For joists spaced at 24″ on-center (or greater), a matched, undamaged TJI® joist may be required on each side of the damaged member due to sheathing span limits. - Reference TJI® Joists Specifier′s Guide (TJ-4000) or ForteWEBTM software to verify the allowable span when installing an additional simple span member beside a damaged continuous span member. 3. Contact your Weyerhaeuser representative for detailed notch analysis.

The primary difference is an additional column included under each joist spacing. The “No Repair” column provides the maximum joist span without an approved nailed-repair assembly installed on the damaged TJI® joist. The “Repair” column provides the maximum joist span with one of the approved nailed-repair assemblies installed on the damaged TJI® joist. Figure 2 provides construction details for the approved Panel Repair. Figure 3 provides construction details for the approved 2x4 Repair. Either repair assembly may be installed along the side of a TJI® joist, centered on the location of the Side Flange Notch.

How to Use These Tables 1. Confirm the damaged TJI® joist complies with Conditions and Limitations on page 1. - Tables assume that the original, undamaged TJI® joist was properly designed as per TJ-4000 or ForteWEBTM software. 2. Determine the distance of the inadvertent Side Flange Notch from inside face of nearest support relative to the as-built span length (ℓ�ℎ). - See Figure 4 above. 3. Select the appropriate table per the location of the Side Flange Notch and the TJI® joist series. 4. Identify the design live load and dead load. 5. Look up the maximum allowable span for the notch location, joist depth, notch depth (𝑑𝑛𝑛𝑡𝑐�), design loads, joist spacing, and repair option. 6. Compare the table span to the as-built span length (ℓ�ℎ). - If the table span is less than the as-built span length (ℓ�ℎ), consider one of the alternative options listed on page 1. General Table Notes • Tables are based on: - Uniform loads. - More restrictive of simple or continuous span. - Clear distance between supports. - Minimum bearing length of 1¾″ end (no web stiffeners) and 3½″ intermediate (no web stiffeners). • Assumed composite action with a single layer of 24″ on-center span-rated, glue-nailed floor panels for deflection only. - Deflection criteria = L/480 live load (LL); L/240 total load (TL). • For continuous spans, ratio of short span to long span should be 0.4 or greater to prevent uplift. ℓ1 4⁄ ℓ1 4⁄ ℓ3 ≥(0.4 × ℓ2 ) ℓ2 4⁄ ℓ3 4⁄ TECHNICAL BULLETIN TB-818 July 2021 (Expires 7/2023) Page 4 of 10 1.888.453.8358 ● www.weyerhaeuser.com/woodproducts Floor Span Tables – Side Flange Notch Located between End Bearing and Quarter-Span TJI® 110 - MAXIMUM JOIST SPAN WITH SIDE FLANGE NOTCH IN TOP FLANGE (END BEARING TO QUARTER-SPAN)[1][2] [1] Confirm accordance with Conditions and Limitations on Page 1 and reference Figure 4, How to Use These Tables, and General Table Notes on Page 3.

Look up the maximum allowable span for the notch location, joist depth, notch depth (𝑑𝑛𝑛𝑡𝑐�), design loads, joist spacing, and repair option. 6. Compare the table span to the as-built span length (ℓ�ℎ). - If the table span is less than the as-built span length (ℓ�ℎ), consider one of the alternative options listed on page 1. General Table Notes • Tables are based on: - Uniform loads. - More restrictive of simple or continuous span. - Clear distance between supports. - Minimum bearing length of 1 ¾″ end (no web stiffeners) and 3 ½″ intermediate (no web stiffeners). • Assumed composite action with a single layer of 24″ on-center span-rated, glue-nailed floor panels for deflection only. - Deflection criteria = L/480 live load (LL); L/240 total load (TL). • For continuous spans, ratio of short span to long span should be 0.4 or greater to prevent uplift. ℓ6 4⁄ ℓ6 4⁄ ℓ6 ≥(0.4 × ℓ5 ) ℓ6 2⁄ ℓ5 2⁄ ℓ5 4⁄ ℓ5 4⁄ ℓ4 2⁄ ℓ4 4⁄ ℓ4 4⁄ TECHNICAL BULLETIN TB-818 July 2021 (Expires 7/2023) Page 8 of 10 1.888.453.8358 ● www.weyerhaeuser.com/woodproducts Floor Span Tables – Side Flange Notch Located between Quarter-Span and Mid-Span TJI® 110 - MAXIMUM JOIST SPAN WITH SIDE FLANGE NOTCH IN TOP FLANGE (QUARTER-SPAN TO MID-SPAN)[1][2] [1] Confirm accordance with Conditions and Limitations on Page 1 and reference Figure 5, How to Use These Tables, and General Table Notes on Page 7.
