How to span 30 feet with wood.
Wood I-joists (sometimes called TJI's) resemble steel I-beams. They are composed of a top and bottom flange (usually a 2×4) with a piece of plywood or OSB fixed perpendicular in between. The biggest benefit I-joists bring are the long span distances you can achieve. A TJI 16″ deep and spaced 16″ o.c. can span about 26 feet!
According to the Deck Joist and Joist Sizing Chart, 2-by-6 joists on 16-inch centers will span 9 feet 9 inches. With joists just 9 feet 7 1/2 inches long, we add in 1 1/2 inches for the ledger thickness, and another 3 inches for the rim joist which will act as our beam, and the span is exactly 10 feet. Perfect. We use a 2-by-6 joists.1. Table is based on continuous floor joist span and simple or continuous beam span con-ditions. If floor joists are not continuous above the beam, take the sum of the joist spans then multiply by 0.8. This is the total floor joist span to consider. 2.
