Sizing a ridge beam.

The length of an LVL beam is governed by its width and depth. Laminated veneer timber is commonly available in widths or thicknesses of 1-3/4″, 3-1/2″, 5-1/4″, and 7″, as well as depths ranging from 5-1/2″ to 24″, including standard and nonstandard depths. The lengths typically run from 4′ to 48′, with increments of 4′ available.

Furthermore, if the vaulted roof is constructed as a hip roof, things get even more complicated. Not only must the ridge beam be supported, but the top ends of the hips must also be supported. And the rafters must have a secure connection to the hips. BC Calc ® performs engineering analysis to help our customers size beams, joists, columns, studs and tall walls for their building projects. It is simple to use, yet flexible enough to analyze a variety of common applications. The user enters the member geometry, adds loads, holes and other relevant data and then selects a product for analysis.

After cutting the plywood, affix a 1×2 fence to the long side. When you finish the jig, write the multiplier on it in red. For the hip-rafter jig, the rise is 6 in., but the run is 17 in. Instead of doubling the rise and run for the hip-rafter jig, multiply them by 1.5, which makes the jig easier to handle.

Sizing rafters differs from sizing joists in 2 ways: The span of a rafter is not based on the measurement along its length. Rather, the span is based on the rafter's "horizontal projection". This is the horizontal distance from the inside surface of the supporting wall to the inside surface of the ridge board.

But a ridge board does not carry any load, so there is no maximum span. A ridge beam, which actually supports the rafters on either side of it, is a different ...The industry markets LVL beams and headers based on the MOE value (modulus of elasticity = E) which along with the size of the beam (moment of inertia = I) determines the stiffness (EI) of the beam. The stiffness of a beam determines how much deflection a beam will experience under a given load. Deflection is a performance criteria established byR802.3 Ridge. A ridge board used to connect opposing rafters shall be not less than 1 inch (25 mm) nominal thickness and not less in depth than the cut end of the rafter. Where ceiling joist or rafter ties do not provide continuous ties across the structure, a ridge beam shall be provided and supported on each end by a wall or girder.Section modulus is defined as the moment of inertia I divided by the distance y from the centroid of the beam to the extreme fiber. So S = I / y. For a prismatic beam, the centroid is at the center of the beam, so the distance y = 1/2 the depth of the beam.
