![]() Using these guidelines will help keep product clean, shed rain, and promote air circulation to dry off any incidental moisture. Tables are for simple span beams (no cantilever) and uniformly distributed loads. PWT LVL products should be protected by keeping the products wrapped, off the ground, stacked, and supported appropriately. Moisture content for in service conditions will vary widely. SPAN TABLES & TECHNICAL GUIDE For further information please visit or call toll free. PWT LVL may swell, shrink, and change shape in response to moisture and adverse weather, even with the additional protection of factory applied sealants. A K: e coefficient of 1.0 conservatively models typical wood column applications. When PWT LVL leaves the manufacturing facility, its dimension tolerances are within the manufacturer’s limits and the product moisture content is between 6-10%. Table capacity values based upon a buckling length coefficient, K: e, equal to 1.0 (rotation free, translation fixed at each column end per NDS Appendix G). Required end bearing length (based on 565 psi) is 3. This is the total oor joist span to consider. If oor joists are not continuous above the beam, take the sum of the joist spans then multiply by 0.8. The guy doing my drawings has suggested I use a 40 5-1/4 X 14 lam carrying beam and hang 14 2X10’s. First floor would not have any interior bearing walls as I’m using 28 scissors trusses for ceiling/roof. 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. As the span length increases, the beam will have to support more weight, so its capacity must be designed accordingly. Table is based on continuous oor joist span and simple or continuous beam span con-ditions. So, ceiling height and clear spans of space are important issues. Table indicates the number of 13/ 4' wide LVL plies to be used for the given application. This slight deviation in dimensions is called tolerance. Span Length: The span length of a beam, or the distance between its supports, can also affect its capacity. Due to the manufacturing processes there may be slight variations between the product and nominal dimensions. PWT Laminated Veneer Lumber (PWT LVL) is produced to specific tolerances based on manufacturing equipment capabilities. ![]()
