How do you calculate a wood beam?
Calculate the maximum bending moment for the wooden beams. The bending moment is the length of the span times the weight to be supported divided by 8. For a beam spanning a 12-foot room and supporting a weight of 600 lbs., the maximum bending moment would be 12 x 600/8 = 900 foot-pounds.

How far can a 4x2 span?
A 2×4 can span a maximum of 6' 7” when spaced 16” apart and used as a floor or deck joist. When used as a ceiling joist or a roof rafter, a 2×4 can span up to 7' 3” spaced at 16”, and 6' 4” when spaced 24” apart. Due to the small spans of 2x4s, they often are not used in horizontal load-bearing capacities.

Where does the UK get its timber from?
Over 90% of timber used in UK construction comes from Europe, where more trees are grown than harvested (source: TTF Statistical Review 2016). Softwood and temperate hardwood forests in Scandinavia, Europe, Canada and North America are stable or growing.
How long are floor joists?
The floor joists are still 12' long but now you can see a floor beam running horizontally across the middle of the house (supported by the lower concrete foundation wall). The picture below shows what the framing for this floor would look like in a three-dimensional perspective.
How wide is a 2x12 planer?
After it comes through the planer it will be 1-1/2" X 11-1/4" (so yes, a 2 X 12 does not measure 2" X 12"). This means that our 4-ply 2 X 12 will be 4 X 1-1/2 inches wide or 6 inches. Therefore a post to support this built-up floor beam will need to be 6" by 6".
Do you need a structural engineer to calculate beam span?
In general, if you are staying within the limits of your beam span tables and floor joist span tables, you will not need to have beam calculations done by a structural engineer.
Common Product Span Tables
Stress grades and timber sizes combine to determine the spanning ability of load carrying members. Span tables allow users to choose an appropriate size and stress grade to achieve spanning needs. For simple construction, such as domestic construction, this can be determined from span table supplements in AS1684.2 and AS1684.3.
