Let's assume you have an LVL beam with a width of 5 inches, a depth of 12 inches, and it needs to support a uniform load of 1,000 pounds per square foot. Review Maximum Safe Span: The calculated maximum safe span for the LVL beam will be displayed on the page.Calculate: Click the "Calculate" button, and the calculator will compute the maximum safe span based on the input values.Input Data: Enter these values into the calculator fields.Gather Information: You'll need information such as the LVL beam width, depth, and the uniform load that the beam will support.Maximum Safe Span: feet How to Use the LVL Span Calculator: Required end bearing length (based on 565 psi) is 3.0 unless the subscript + is shown. 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. ENGINEERED WOOD PRODUCTS (EWP) LVL SPAN AND SIZE CHARTS. 2 Stress grade, and wet service conditions.Enter the required information below to calculate the maximum safe span for LVL beams or joists: LVL Beam Width (inches): Table is based on continuous oor joist span and simple or continuous beam span con-ditions. Note: The span chart below is an example of how spans charts are presented. Because building code and lumber spans are updated from time to time, you should always check to make sure the span chart you are using is up to date. See the applicable code section, or the NDS to confirm the span chart you are using is correct.ĭimensional Lumber Deck Beam Spans Supporting a Single Span of Joists with or without Overhangs:Īssumes 40 psf live load, 10 psf dead load, L/360 simple span beam deflection limit, cantilever length L/180 deflection limit, No. The longer the joist, the more area of deck the joist supports, and thus the beam supports more area as well. In addition, many residents prefer the fell of a deck that is designed for higher loads. VERSA-LAM ® cover veneer lumber (LVL) beams or headers eliminate twisting, shrinking and split, and deliver flatter, calmer floors both structures. Building codes for residential decks only require 40 psf in some areas, but check your local requirements to make sure you are aware of any additional local guidelines. ENGINEERED WOOD PRODUCTS (EWP) LVL SPAN AND SIZE CHARTS. The above table of LVL sizes offers a detailed beam sizes chart for engineers to easily scroll and find what they’re looking for. Beam span maximums are based on a maximum anticipated live load as well as other factors. 1. Below we have included common product span tables for: For other, more complex, load condition spans use our free. Select the application type and enter the span length to get the required dimensions. For simple construction, such as domestic construction, this can be determined from span table supplements in AS1684.2 and AS1684.3. Use these calculators to size Trus Joist TimberStrand LSL and Parallam PSL beams and headers for U.S. Fewer posts on upper-level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. Span tables allow users to choose an appropriate size and stress grade to achieve spanning needs. The span of a beam is dependent on a few variables: The grade and species of lumber, size of lumber and the load it carries.
