How to size a ridge beam.

A ridge board is an essential component of a roof structure located at the highest point of the roof. It supports the upper ends of the rafters, which are the sloping beams forming the roof framework. However, it is important to note that a ridge board is not load-bearing and does not provide any load-bearing capacity to the roof framing system.A structural ridge counteracts the down and out force you are talking about. That is why the sizing of the ridge beam is critical. In a typical stick frame roof the rafters transfer loads down at the ridge and walls. This force pushes the ridge down and causes the rafters to exert force out against the walls.If you’re an off-roading enthusiast, you know how crucial it is to have the right tires for your adventures.

In order to calculate the beam depth and width as per the thumb rule take this example. Span of LVL Beam = 20 ft. Depth of Beam as per thumb rule = (20 x 12) / 20 = 12 inches. Width of Beam = 12/4 = 3 inches. Hence one need 12 inches thick LVL beam or 3-1/2 “ x 11-7/8” size up to span of 20 ft.Ridge beam vs truss for 30 foot span.

UnitLoad is the combined dead and live load per square foot. BeamLength is the length of the beam in feet.The Ridge Beam Calculator calculates the appropriate size of the ridge beam based on factors such as roof slope, length, building width, and allowable stress, using mathematical formulas derived from structural engineering principles. 4.

In addition, a 8×18 wood beam can span from 24 to 26 feet, while a 10×18 wood beam can span from 28 to 30 feet.

The maximum spans in the table above are for the horizontal distance the rafter can span (NOT the diagonal distance or actual length of the rafter).
