Typically a #2-SYP 2×8 triple deck beam can allow to span a maximum distance from 10 to 11 feet with total load of 50 psf (40 psf live load + 10 psf dead load) with deflection limit L/360.

Typically a #2-SYP 2×6 triple deck beam can allow to span a maximum of 8 foot with a total load of 50 psf (40 psf live load + 10 psf dead load) with a deflection limit of L/360. Moreover, the maximum span for a triple 2×10 beam is typically about 13 feet, while the maximum span for a triple 2×12 beam is typically about 15 feet. In general, the maximum span for a triple 2×6 beam is typically about 8 feet, while the maximum span for a triple 2×8 beam is typically about 11 feet. How far can a triple 2×6, 2×8, 2×10 and 2×12 beam span How far can a triple 2×6, 2×8, 2×10 and 2×12 beam span.Joists are technically beams that typically spans relatively short distances compared to beams and are made of wood, steel, or engineered wood or lumber. It is like the skeleton/ framing of a building that supports the load which the floor is built to bear. Their function is similar as beams, except floor joists are supported by wall, foundations, or beams framing.īeam carries the load and transfer the dead load of the subfloor and floor finishes and live load of people, furniture and furnishings to walls, headers, or foundation walls. Floor joists are typically a horizontal structural member that runs across an open space of building on supporting wall or studs. Assumed composite action with a single layer of 24' on-center span-rated, glue-nailed floor panels for deflection only. Clear distance between supports Minimum bearing length of 1' end (no web stiffeners) and 3' intermediate. Grade 1 lumber have higher strength than other grade Lumber due to fewer knots.Ī triple 2×6 are made when three 2×6 beam are nailed together, a triple 2×8 are made when three 2×8 beam are nailed together, a triple 2×10 are made when three 2×10 beam are nailed together and a triple 2×12 are made when three 2×12 beam are nailed together.ĭeck beam provides structural support to floor joists can be define as several small beams. More restrictive of simple or continuous span. Southern yellow pine is strongest species of wood that can span more distance compared to other species of wood. There are different depth of deck beam made of timber are used in floor construction such as 2×6, 2×8, 2×10 and 2×12 etc made of different species of wood (southern yellow pine & Douglas fir) and different grade such as grade – 1, grade – 2, grade – 3.
