Beam spans in this guide are typically measured from center-to-center of supports except for door and window headers. 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. This span table excerpt shows two possible sizes of built-up floor beams (2 X 10 and 2 X 12). The full table shows more lumber sizes. It also shows the maximum that the beam can span for various numbers of such pieces of lumber built together (this is indicated by 3-ply, 4-ply and 5-ply).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 …Maximum floor joist span for No. 1 and No. 2 Grade of Douglas fir are indicated below.
