Ridge beam sizing is based on the span of the beam between supports, and the amount of roof load supported by the beam. This translation is the key to any structural sizing problem. We will consider only distributed loads. 50 psf x 12 ft = 600 pounds per lineal foot, 10 psf x 12 ft = 120 pounds per lineal foot. The loads delivered to the header are: 30 psf x 6 ft = 180 pounds per lineal foot, 10 psf x 6 ft = 60 pounds per lineal foot. Engineered Wood manufacturers are quick to point out that their products provide superior strength and stiffness. duration of load is 1.15 (snow) tributary length = 12’-0” (exclude outer 6 ft of rafters which bear on outside walls) the ridge beam

It has been my experience to never use a beam smaller than a two ply 2 x 8.

But you can trick WSDD tables into giving you values for double or triple 2-by beams with other deflection limits. Span tables for engineered wood are used in a very similar way as those for sawn lumber.

Using span tables, I have sized several structural elements for 2 climatic conditions. The job of headers and beams is a simple one. Note: a single 2×6 will support 347 pounds per lineal foot of beam.

Tables are limited to whole-foot spans, but the values can be interpolated for fractional lengths.

2) 2nd floor header with a 4-foot span 9 0 obj << /Length 10 0 R >> stream Formulas that determine the allowable span and size of a beam rely on a host of variables like species, grade, size, deflection limit and type of load. The 18-foot garage header for our house weighs in at 380 pounds. Live and dead loads listed in the building code for roofs and floors are approximations of distributed loads. Tutorials, Calculators, and Building Codes. Let’s trace distributed loads for several different houses.

And the garage door header is based on a 2-car garage-door opening. But the upside is that 2 workers can usually handle the weight of each lamination as it is assembled. Call Anthony Forest Products direct to find a distributor.

TimberStrand FrameWorks Header, a laminated strand lumber (LSL) made by TJM, is the latest entry into the structural header and beam competition.

But overall, for short spans, sawn-lumber is tough to beat. Off hand, Now if you have done any looking around this site, you'll quickly see that I am not a fan of using a ridge beam in shed construction.
