Subsequently, How far can a 11 7 8 I-joist span?
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.
Can I make my own I-joists?
Can you drill holes in I-joists? You can drill the holes anywhere along the length of the joist (first photo). If you have manufactured I-joists, you can drill holes up to 1-1/2 in. diameter almost anywhere in the web area (the area between the flanges). Just stay 6 in.
How strong is an I joist?
Are I joists stronger than timber? I joists are specifically designed to offer strength in areas that dimensional lumber is incapable of. They can span greater distances, and are considered to be 50% stiffer than dimensional timber under traditional frame spacing.
Are joists good? I-joists can be a great product for a new home project. Your carpenters will like them because they are lighter…which makes it possible for one person to install. And similar to the floor truss, I-joists can span greater distances than 2×12’s.
What is the difference between a beam and a joist?
Both beams and joists are horizontal structural members used to frame buildings and protect the structural integrity of the walls. Joists can be thought of as several small beams that may rest on top of beams or be fastened to the sides of beams, whereas beams may receive their loads on a vertical or horizontal face.
Can TJI joists be cut? Fire cuts are permitted on TJI joists provided: The TJI® joist has sufficient bearing, The cut does not extend past the inside face of the wall. The joist has full depth lateral support.
Can you notch TJI?
Notch will only be allowed in a TJI joist member of one ply. TJI product can only have one notch per joist member. Notch will only be analyzed when the length parallel to the joist member span does not exceed 4 inches.
Can you cut holes in TJI? All holes larger than 1 ½” must be spaced at least 12” from the edge of the hole to the inside face of bearing. Although cutting holes larger than 1½” in TJI® joist webs near end bearings is not permitted in the table, we recognize that this condition does arise.
What are TJI joists made of?
TJI vs LVL
TJI joists have a top and bottom flange made of solid or finger-jointed wood with a perpendicular sheet of OSB or plywood (LVL) in between. LVL (laminated veneer lumber) looks more like a plank except it’s made up of layers of thin veneer glued, heated, and pressed together, like plywood but much thicker.
What is stronger LVL or LSL?
LSL is typically less expensive than other engineered wood beams. Due to its high allowable shear strength, LSL beams have the capacity for larger penetrations than other engineered wood beam options. While not as strong as LVL or PSL beams, LSL is generally cheaper and is ideal for short spans.
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.
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.
Can you use 2×10 for floor joist?
2×10 floor joists are designed to hold a 40 pound per square foot (psf) live load, plus a 10 psf dead load. Span tables indicate distance maximums for floor joists, with distances indicating the maximum length a 2×10 can span while still able to hold a 40 psf live load.
Are beams stronger than joists? As the main weight-carriers, beams are more solid and substantial compared to joists. A proper beam should transfer the load to the vertical elements, which explains why most beams in buildings are made from steel, combined dimensional lumber, or engineered wood.
What is AC joist?
Bailey C-Joist Floor System components provide an economical, lightweight alternative to open web steel joists, engineered wood « eye » joists, cast-in-place or hollow core floor assembly systems. C-Joists come in a variety of depths, flange sizes and steel thicknesses.
Are joists load-bearing? Located between walls, beams, and foundations, floor joists are structures that support floors and most easily identified in a building’s basement or attic. Walls that run parallel to joists are not typically load bearing, whereas walls that run perpendicular to the joists are most likely load bearing.
What does TJI joist stand for?
TJI stands for Truss Joist I-Joist. The engineered wood I-joist can be used for joists or trusses, are stronger and lighter than dimensional lumber of similar widths, and can span greater distances. The truss-joists are engineered to resist twisting and warping, and won’t shrink like dimensional lumber.
How do you cut a TJI joist? How To Quickly Cut TJI Joists

How do you reinforce TJI joists?
The best way to strengthen floor joists from underneath is to make a supporting mid-span beam or wall beneath the wobbling joists. Using jack posts or 6×6 posts and 2×10 or 2×8 beams perpendicular to the joists will solve any wobble and ensure your joists never move again.
Can I joists be notched? Joist Notching Rules
The maximum depth of a notch at the end of a joist (where it rests on a wall or beam) can’t exceed one-quarter of the joist depth. … Limit the length of notches to one-third of the joist depth. No notching in the middle third of a joist.
What is the maximum notch typically allowed in a beam?

Notches at the ends of the member shall not exceed one-fourth the depth of the member.
