That said, this situation sounds like something an engineer could knock out pretty quickly…especially those who work mainly in the residential sector. For a floor beam, select the appropriate span table for one or two floors, identify the. Laminated veneer lumber typically comes in 1-3/4, 3-1/2, 5-1/4, and 7 widths or thicknesses, and depths of 5-1/2 to 24, including standard and nonstandard depths. By using these tables you can find the most optimal cross-sections for the structures. The tables below describe the most common measurements according to local requirements for different Kerto LVL structures in floors, roofs and walls. Continuous Span Beams are beams supported at three or more points along their length. Single Span Beams are beams supported at two points only. engineer will want do all calculations himself/herself. The distance an LVL beam can span depends on its width and depth. Span tables for Kerto® LVL beams, panels, studs and I-joists help designers work faster and more efficiently. For the purpose of using these tables, span may be interpreted as the clear distance between supports measured along the beam. Resists warping, splitting and shrinking while supporting heavy loads. On the other hand… interesting to work out how to do it and see if the structural engineer comes up with the same answer! MICROLLAM® LVL BEAM BENEFITS: Uniform and predictable. 2.1E Billet Beam Columns 2. I doubt a structural engineer will just write “See Rhino, GH, Karamba model that the customer has supplied himself” and give you a big discount for saving time! PWT Treated Joist Span Tables PWT Treated Sill Plate Flyer Specifications Safety Data Sheet Code Reports. A beam 16’ long, carrying 300 PLF, with 1.9E material will deflect 0.0344 inches less ( ) under total load compared to the same beam with 1.8E material. It was frustrating because it looked like something I could have worked out myself but it was the calculations that bulding control want to see. In some applications, a 1.9E or 2.0E beam cannot be used as a substitute for a 1.8E beam that has superior strength properties (Fband Fv). VERSA-LAM ® laminated veneer cut (LVL) beams and headers eradicate rotational, shrinking and splitting, and provide flatter, quieter floors and structures. 2 Stress grade, and wet service conditions.I’m not 100% sure of this but I think you won’t save any money by doing this because for building regs you need to show the calculations for the beam done by a qualified structural engineer so even if you took a GH load analysis to a structural engineer they are unlikely to then give you a discount on the calculations that they would still have to do.įor every steel used in our house we got the spec sent back from the structural engineer straight away and when we paid the invoice we got the calculations. ENGINEERED WOOD PRODUCTS (EWP) LVL SPAN AND SIZE CHARTS. 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. 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. Beam span maximums are based on a maximum anticipated live load as well as other factors. 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.
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.
