Installation details can be found throughout TJ-9000 (EAST) TJ-9020 (WEST) - our beams, headers, and columns specifier’s guide.Īs with most things, this document has its limitations. Required information to adequately size a member:

Clear Span - the distance between the two inside surfaces of the span supports the distance that is unsupported, or simply, the opening.

Bearing - a structural element that supports weight/loads.

Assumed composite action with a single layer of 24' on-center span-rated, glue-nailed floor panels for deflection only. Clear distance between supports Minimum bearing length of 1¾' end (no web stiffeners) and 3½' intermediate.

Dropped Beam - a beam that will be below the members it is supporting More restrictive of simple or continuous span.

Flush Beam - a beam that will be in the same elevation as the members it is supporting.

For exterior/wet applications, see TJ-7102 The wood is placed in a depressurized holding tank that removes the air and replaces it with a preservative.

Pressure Treated - wood that has been infused with chemical preservatives to protect the wood from rot.

6 Trus Joist invented the composite steel and wood open-web truss over forty years ago. TJI joists offer the workability of wood for fast, easy nailing using traditional framing tools. TJI ® joists work exceedingly well in cantilevered applications. Microllam LVL Beams Microllam LVL Headers Parallam PSL Beams Parallam PSL Columns. Open-Web Trusses and Long-Span Applications Parallam. Manufacturers commonly produce the LVL with standardized depths of 241 mm, 302 mm, 356 mm, 406 mm, 476 mm, and 606 mm. The most common thickness of LVL is 45 mm but LVL thicknesses vary from 19 mm to 178 mm. Beam must be centered in building if floor joists are continuous over. The LVL panels are cut into a range of widths depending on the products end-use. Ratio of short span to long span should be greater than 0.4. Span is based on the more restrictive of simple continuous beam span. Document Types: Design & Specification Categories. Table indicates the number of 13/ 4' wide LVL plies to be used for the given application.

Nomenclature/terminology of this document: Description: Design information for TimberStrand LSL, Microllam LVL and Parallam PSL. Whether you are a designer, builder, or a DIY'er, this document is intended to provide us with the necessary information to size a support member quickly and adequately for you.

Sometimes renovations are more challenging like replacing a load-bearing wall or adding an addition to the existing structure. Sometimes this means something simple, like painting, or a little more difficult, like replacing the floors. Verify adequacy of beam in uniform load tables prior to using values listed below.

It is not uncommon for homeowners to renovate their residences.
