Joists are used horizontally as a support for a ..., Based on the information you provided, the minimum size of the ridge beam for your roof is 2x10 southern pine LVL.Here is the calculation:Total load = snow load + live load + dead load = 40 psf + 30 psf + 10 psf = 80 psf Required section modulus = Total load * Span^2 / 8 * Allowable bending stress = 80 psf * 15^2 / 8 * 1650 psi = 0.01859 in^3., Ridge Beam Sizing - LVL or Lumber. Building a 12' x 12' shed with gable roof @ 5/12 pitch, ridge beam design for open ceiling, no rafter ties. 20 lb snow load for this area. No permits, none of that, but would like to meet IRC code. This is a personal project, not for a customer. I can't navigate a span table to save my life and I don't trust ...
