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. Maximum cantilever for joists and beams beyond supports is 24 (600mm).

According to this If I have a two 2x10 beam spanning 8 I can have a 2 beam cantilever on each end.
