How to size a ridge beam.

If you are calculating the rafter length from the center of the ridge beam, you will need to subtract half of the thickness of the ridge beam from the top end of the rafter. For example, if the ridge beam is 1 1/2 inches thick, subtract 3/4 of an inch from the upper pitch cut, resulting in a new upper pitch cut parallel to the first.Steel beam end bearings to be located on substantial load bearing masonry walls or piers. Plan area of bonded masonry supporting steel beam to be greater than or equal to 0.1m². The minimum end bearing length at supports to be 100mm.

The rule of thumb is that the gusset should be twice the width of the wood you use for your rafters. So roughly 7 – 8” long for a 2×4. Each side of the gusset will be 8” long, but only 8” tall. Layout your sheet of plywood on sawhorses. Facing the long side of your material, measure down from the top edge 8”. You can size your ridge by being over conservative, using the 60 psf snow load, unfactored by ASCE-7, a dead loading (from what you've given) of 12 psf, thus totaling 72 psf. With your tributary area given, your beam needs to be sufficient for handling 288 plf for its 14 foot span.Create a brace for your ridge board by nailing a 2-by-4 board up the center of the gable-end wall. The board should measure taller than the wall and roof rise combined. Place your ridge beam across the walls or rafter ties perpendicular to your rafter layout.
