Triple 2x12 beam span table
The rule of thumb around here used to be 1 inch of header depth per foot of span (doubled 2x6 for a 6' opening, 2x8 for 8', etc.). This was to support 1 floor load or 1 roof load. For a floor and a roof, use the next size up. So a double 2x12 could support a 10' first floor opening with a second floor and roof load on it.

50 psf x 12 ft = 600 pounds per lineal foot. roof dead load: 10 psf x 12 ft = 120 pounds per lineal foot. total load: = 720 pounds per lineal foot. Girder Example. The center beam carries half of the floor load, the partition load and half of the second floor load. Live and dead loads are given in the building code.This span table excerpt shows two possible sizes of built-up floor beams (2 X 10 and 2 X 12). The full table shows more lumber sizes. It also shows the maximum that the beam can span for various numbers of such pieces of lumber built together (this is indicated by 3-ply, 4-ply and 5-ply). A 3-ply with 2 X 10s would mean that three 2 X 10s are ...Since the 26-ft.-wide building is 6 ft. wider than the 20-ft. width from the table, calculate the following: 0.75 in. per ft. × 6 ft. = 4.5 in. Subtract the above number from the header span for a 20-ft.-wide building to find the allowable header span for a 26-ft.-wide building: 3 ft. 11 in. – 4.5 in. = 3 ft. 6.5 in.
Joists & Rafters Simplified maximum span tables for selected visual and mechanical grades of Southern Pine lumber in sizes 2×4 thru 2×12. Listed are 46 tables based on common loading conditions for floor joists, ceiling joists and rafters. View Joist & Rafter Tables Headers & Beams The Code requires a Live Load of 40 lbs. per square foot (psf) plus a Dead Load of 10 psf for a total load of 50 psf. You indicate the beams are 8’ on center, so the total load on each beam is: 50 psf x 8’ (4’ on ea.side of beam) = 400 plfSpan Tables Overview Resources provide a simplified system to determine allowable joist and rafter spans in one- and two-family dwellings, and the companion supplements for tabulating allowable bending and modulus of elasticity design values for visually graded and mechanically graded dimension lumber.SPAN TABLES.
