According to TJI’s span table, switching to deeper 11-7/8 inch joists (a nominal 2×12), even when spaced at 19.2 inches on-center, enable you to go as long as 17 feet, 4 inches and still achieve L/480.
How far can you span with a tji? [6] Total load deflection limited to L/240 and live load deflection limited to L/360; no composite action considered. [7] Maximum on-center spacing for bracing of TJI® 110 is 32u2033 o.c.; for bracing of all other TJI® joists use 36u2033 o.c. [8] Maximum clear span limited by scope of 2018 IRC Table 802.5.
Similarly, How far can you span a 12 inch I joist? You can go up to 17 feet, 9 inches if you use 9-12 inch-deep joists that are 12 inches on-center.
How far can an I joist span without support?
The length of one 2×10 joist span depends on the wood species and how far apart it is from the next 2×10. A 2×10 southern yellow pine joist can span 16 feet and 1 inch without support. A doubled 2×10 beam can span 11′ without support for a deck that is 4′ wide.
Which is better L 360 or L 480?
I prefer to go with a span chart that uses L/480 for the live load. That means L/360 is implied for the total load deflection, and it will result in much better floor performance. With roof trusses, the typical deflection limit is L/240 for live load, and L/180 for total load.
How far can a 16 tji span?

How far can you cantilever a TJI?
TJI® joists are permitted to be cantilevered up to 1/3 the adjacent span if not supporting concentrated loads on the cantilever. Cantilevers exceeding 4 feet may require special consideration.
Are TJI joists good? Engineered to provide strength and consistency, Weyerhaeuser’s Trus Joist® TJI® joists are one of the most fundamental components of a solid, high-performance floor system. And with their light weight and long lengths, TJI joists are faster and easier to install than traditional framing, which can save time and money.
Are TJI joists more expensive?
Truss joists are much more expensive than engineered I-beams. They are also substantially heavier, as they are all solid lumber plus metal plates.
Are trusses stronger than joists?
Pros: Span longer distances than traditional joists, removing the need for walls in some areas. Lighter weight. Stronger than traditional joists.
