The 1.15 or 15% ‘Repetitive Member Factor’ (Cr) recognizes that the built-up beam, predictably, is stronger than timber of comparable dimensions, and is usually factored into span tables. The bottom line then is that although a 6×6 beam is 22% larger than a triple 2×6 beam of the same length, the ‘Repetitive Member Factor’ of 15% decreases the …The Code requires a Live Load of 40 lbs. per square foot (psf) plus a Dead Load of 10 psf for a total load of 50 psf. You indicate the beams are 8’ on center, so the total load on each beam is: 50 psf x 8’ (4’ on ea.side of beam) = 400 plf1 There's no such thing as a wooden I-beam. There are I-joists, but they carry relatively little load. LVL (laminated) beams have a substantially higher load rating than solid wood. …I am removing a center post on my patio cover to create a clear span of 15'. The current beam is 2 2x8s with three 4x4 posts. I have had a engineer friend calculate the load for the roof (pic attached). His recommendation is to replace the beam with 3 2x12s to support the roof loads and eliminate the middle post. Posts will become 6x6s.Use the drop downs below to select your loading, house width, and material to calculate the appropriate size of TimberStrand or Parallam ridge beam.
