Our next step is to check if this deflection is less than the allowable deflection for our given beam span. For that, we use the deflection criteria provided by the 2012 International Building Code, stating that beams under a combination of dead load (permanent load) and live load (loads that can vary in time) should at most have an allowable deflection equal to the span of the beam divided by ...

According to the 2012 IRC codes any beam, joist, or header shall never have a bearing of less than 1 1/2″. Anything 5′ and above we always at least double cripple. On longer spans the beam may require much more bearing space as indicated by this table. Fastening. Beams of more than one ply must be fastened together with either nails or bolts.

Then drop down to find the appropriate Fb value for the span. As the table shows, no 2×8’s meet the span and spacing requirements, but a 2×10 with an E of 1,300,000 psi and Fb of 1093 psi can span 15 feet 3 inches – more than enough. A 2×12 with an E of 800,000 psi and Fb of 790 psi also works, since it can span 15 feet and 10 inches ...

A Work in Progress. The 2015 IRC simplified sizing deck beams with the introduction of Table R507.6 “Deck Beam Span Length.” That table presented the maximum spans for a series of multi-ply, built-up-dimensional-lumber beams from a double 2x6 through a triple 2x12, with beam spans based on the span of the deck joists from the ledger to the beam.
Sizing deck beams got a lot easier with the publication of the 2015 International Residential Code.Deck builders can now refer to Section R507.6 Deck Beams and Table R507.6 Deck Beam Span Lengths to determine the size of 2-ply and 3-ply built-up beams made from 2×6 through 2×12 lumber.

Lumber span tables are valuable guides which provide the maximum allowable spans for different types and sizes of Southern Pine and pressure-treated lumber under various load conditions. They help you determine how far a wooden beam or joist can span between support points, such as walls or beams, without compromising safety and structural ...
According to our beam span chart resource, the span of a beam is dependent on a few variables: the species of lumber, size of lumber, and the load it carries. Choosing Wood for Your Deck Beam. It’s important to choose a strong, dense wood for your beams. Some of the most common types of wood used for beams include: Southern Pine;
For a 4x10 beam of #2 EWP apply the size factor of 1.2 to arrive at a Fb of 690 psi. Update that value in the calculator, and set the beam depth to 10". Going through the same process you will find that the maximum load for the 4x10 is 1970 lbs. For a 4x12 beam the shape factor is 1.1, resulting in a Fb of 632.5 psi.
