Span is based on the more restrictive of simple continuous beam span. Use ForteWEB to determine solutions for conditions beyond the scope of. Table indicates the number of 13/ 4' wide LVL plies to be used for the given application. For Canada switch to Canada Sizing Table Lookup. If a lumber rafter of similar or less size can work here, then the LVL definitely can as well. Use the drop downs to select your floor load, framing length, and material to calculate the appropriate size of TimberStrand or Parallam beam. Using your numbers, the rafter span you are looking for in the code table 10'-1 11/16" 2 Stress grade, and wet service conditions.An LVL is manufactured without the natural defects that can be found in lumber, therefore an LVL can deliver better performance than a similar sized piece of lumber. 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. Span Tables Index of span tables í í Scope of this publication This Design Guide and Load Tables assist in the selection of SmartLVL® beams for most of the common structural arrange-ments met in domestic construction. Methods of developing lateral restraint and providing adequate support, adequate anchorage against wind uplift, and. The longer the joist, the more area of deck the joist supports, and thus the beam supports more area as well.

Use ForteWEB to determine solutions for conditions beyond the scope. In addition, many residents prefer the fell of a deck that is designed for higher loads. Use the drop downs to select your roof load, house width, and material to calculate the appropriate size of TimberStrand or Parallam header. Section R507.6 calls for the built-up beams to be fastened together with a minimum. Check with your local code official, or simply drop back to the shorter value in the table and assume the allowable span is 7-7. 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. joists, you know the beam can span somewhere between 7-7 and 8-0, but you don’t know exactly where. Beam span maximums are based on a maximum anticipated live load as well as other factors. RigidLam® LVL Floor Span Tables Riddle OR. As a general guideline, for a 30-foot span, it is typically recommended to use LVL beams with dimensions of 5-1/4 × 13 1/2 or 5-1/4 × 16. 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 size of LVL beams required for a 30-foot span is contingent on several factors, including the anticipated load and compliance with local building codes. 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.
