Typically a #2-SYP 2×8 triple deck beam can allow to span a maximum distance from 10 to 11 feet with total load of 50 psf (40 psf live load + 10 psf dead load) with deflection limit L/360. So, a triple 2×8 deck beam can span maximum distance of 10-11 feet.
These nine beam spans are for built-up beams made up of either 2X8, 2X10 or 2X12 dimensional lumber nailed together as either 3, 4, or 5 ply beams. For example a 3-ply 2X8 beam would use three 2X8s nailed together side by side.
30 cze 2022 · Use this wood beam span calculator to check a wood beam of a particular size and length to see if it can support a given uniform linear load by comparing its allowable and required bending and shear stress.
How Far Can a Triple 2×10 Beam Span? A triple #2 – 2×10 beam of Southern pine can span between 7’-6” and 13’-0” with a live load of 40PSF depending on the joist span. Using DF-L, Hem-Fir, or SPF and the span changes to 7’-2” and 12’6” under the same conditions.
The span of a triple 2×8 beam is determined by a number of factors, including the type of wood used, the grade and strength of the wood, the spacing between the beams, and the load that will be placed on the beams. In general, a triple 2×8 beam can span anywhere from 8 to 14 feet.
How to build a three-ply laminated 2x10 beam and what fasteners to use. by Patrick. (Long Island, NY) I am building a ground level deck (max 24" of the ground). It is L shaped and will have 2 long beams (27.5' and 31'). The beams will be 3-ply PT SP#2 2x12's using 12' long lumber cut to fit the distances between the supporting posts.
