How to size a ridge beam.

May 15, 2004 · In a roof with a structural ridge beam, there is not lateral thrust, i.e. the rafters aren't trying to push the walls out. The roof load is carried on the ridge and on the walls, and there is no need for collar ties or ceiling joists to resist lateral thrust. In a roof with a ridge board, there is lateral thrust.

I will be using 6×6 poles on 8ft centers with 2×6 framing in between, with 1/2” osb on the outside. My plan was to nail and glue 2×12’s with 1/2” ply wood in the middle to make a 48ft ridge board “this will be supported by 4×4’s and 2×6’s”.40ft x 12″ = 480″ (length in inches) ÷ 24″ on-center = 20 rafters. After getting the answer, add 1 for the ‘0’ rafter and multiply it by 2. You’ll get the number of rafters needed for your roof. 40ft x 12” = 480” ÷ 24” on-center = 20 rafters + 1 = 21 rafters per side x 2 = 42 rafters. Get a Free Roofing Estimate.Saturday, July 21, 2018.

A ridge beam is a horizontal structural member that runs along the peak of a roof. It is typically made of wood or steel and is designed to carry the load of the roof’s weight and transfer it to the supporting walls or columns. Ridge beams are often used in larger and more complex roof designs where the span between the walls is considerable.The ridge board is dependent on the truss-action of the closed conventional roof system. A ridge beam on the other hand is a structural member at the peak of an open (cathedral) ceiling system that must be designed by an engineer to support the rafters along its length and transfer the roof loads to supports.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.All answers reference hip "beam". The table in the WFCM is for hip "beam".
