No matter where they’re used, they install quickly with little or no waste. ![]() 16 Lintel span Ceiling Joists B Rafters A Strutting Beam (or Girder Truss) Hanging Beam Lintel to. The top flange of the Lintel is assumed to be laterally supported at mid-span. The Strutting Beam is assumed to be supported by the Lintel at mid-span. They can easily be built-up on site to reduce heavy lifting. The length of the rafters are assumed to be within 15 of the Strutting Beam span (B). 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. Microllam® LVL beams work well in applications all over the house. 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.
