Sizing a ridge beam.

The bearing walls that are parallel with to a ridge beam must have the stiffness to resist the the outward pressure exerted on the walls by the joists. This can be provided by horizontal ceiling rafters that connect between the walls or a concrete block wall with a tie beam. So a ridge board does not have to be supported.

Sizing a ridge beam. Things To Know About Sizing a ridge beam.

Ridge beam size ≈ (5 * 10,000 * 20^2) / (8 * 2000) ≈ 125 inches; So, the recommended ridge beam size is approximately 125 inches for the given roof span, load, and LVL 2.0E material strength. Please note that this is a simplified example, and actual ridge beam calculations may involve additional factors and structural engineering expertise.In beam-speak you say: this header must carry X-pounds per lineal foot.

Engineered wood components are sized using span tables that match various spans to pounds per foot of beam.My question comes from building inspector on beam span. My patio is 16'x16', 4/12 pitch, 4x8 rafters 32"OC, 12" Overhang, 8x8 posts, 4x12 side girders. One end will be tied into addition and the other end I want open. I planned to use 4x12 Ridge Beam, but inspector is not sure on span rating and wants to go with triple 2x12 or 2xLVL. The 2012 IRC code calls for a minimum of a 32″ O.C. staggered pattern with at least a 3″x.120″ nail. We have learned from our experience to use at least a 3 1/4″‘x.131″ groove shank nail in a column of four every foot apart down the laminate.
