Sizing a ridge beam.

The built-up members must be connected to transfer load from the loaded ply into the other plies. Page 303 of our Fastening Systems catalog, C-F-14 provides allowable uniform load tables for side-loaded multi-ply assemblies using LVL, PSL or LSL material. The calculation for the allowable load applied to the outside ply of a multi-ply beam is:

With 20 span, it would be 8400lbs.Ridge beam sizing is based on the span of the beam between supports, and the amount of roof load supported by the beam. A ridge board is a non-structural member that serves as a prop for opposing rafters to rest against and connect to. Ridge boards can only be used in roofs with slopes from 3 in 12 up to 12 in 12.If you have a 30-foot span, it is important to know just how long a beam you will need for support. There is a good rule of thumb for this: divide your span (in inches) by 20. So, if your span is 30 feet (or 360 inches) you would divide that by 20 to come to 18 feet. Generally, it will be between a third and half of your overall depth.Ridge boards and ridge beams are often confused with one another. They are not the same thing, however.
