Strutted lvl beam span table4/3/2024 beam span is 10 ft and the span carried is 24 ft. So is there any reason why I should go with a flush versus the hanging beam? If you recommend the hanging, what is the best method to hang each joist?įYI. Tables W-1 and W-2 of Design Values for Joists and Rafters, a supplement to these span tables, provide such values for them ostc ommonly used framing sizes. Lateral support of beam compression edge is required at intervals of 24 o/c. 3100F b-2.0E 3 ¹ WEST FRASER LVL ALLOWABLE DESIGN VALUES 1. All 16, 18 and 24 beam depths are to be used in multiple member units only. For example, you can span a 1 grade (no knots) southern yellow pine joist a greater distance than a 2 grade of the same species (with knots). Know more nearly Engineered Wood-based Products by downloading the correct install and/or specifier leadership within your area and get access to spanned charts for BCI ® Joists press Versa-Lam ® LVL. Lateral support of beam is required at bearing locations. The lengths and sizes of joists vary depending on the species and quality of the lumber used. The flush beam installation, I feel has a greater risk of damaging the joists and struts when when the bracing is removed and I will need to add much more additional bracing while the beam is put in place. Use of these span tables requires reference to the applicable design values for the various species and grades of lumber. Considerations when using the Rafter and Joist Span Tables. The hanging beam sounds like an easier less invasive method. Option 2 is the flush mounted beam in which I would need to remove the struts and reconfigure them to attach to the new beam, then I would need to remove the 1圆 bracing on the splices and cut in the new beam and add hangers for the joists. To find the span of a wood beam, lets say a 2'×8' beam (with actual measurements of 1.5'×7.5' ): Determine your wood beams modulus of elasticity (E). I am contemplating whether I should leave the splices and struts alone, and simply hang the joist from an LVL beam which will be point loaded on an exterior wall on one side and an interior wall which sits directly above a foundation pier on the other. Roof support struts are also mitered together and meet on top of the wall attached to side of every other ceiling joist(see photo below). Beam must be centered in building if floor joists are continuous over. 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. The wall supports 2圆 ceiling joists which are butt spliced at the wall and sandwiched with 24" 1圆's. Table indicates the number of 13/ 4' wide LVL plies to be used for the given application. Use of the Wesbeam data for lookalike or substitute products can result in unsafe or unsatisfactory performance. I could use a little assistance in making a choice between a hanging beam or flush beam in the attic so I can remove a wall. What Sizes Do LVL Beams Come LVL beams commonly are available in widths of 1-3/4, 3-1/2, 5-1/4, and 7. The span tables and other technical data provided are only applicable to LVL manufactured by Wesbeam and should not be used for lookalike or substitute products.
