Install with two 6d common nails per end.
Tji floor joist bridging.
Simpson strong tie tension bridging galvanized steel the ltb s are used in floor systems to resist the overturning of floor joists and features a staggered nail pattern.
I ve been told for many years that the typical tji system does not require bridging or blocking because of their structural integrity or similar expression.
Featuring trus joist tji joists for floor and roof applications uniform and predictable lightweight for fast installation resource efficient resists bowing twisting and shrinking significantly reduces callbacks available in long.
The most obvious solution is to add a beam supported by posts under the floor joists.

Consequently they do not see any significant benefit from bridging.
Tji 110 210 230 and 360 joists δ 22 5 wl4 2 el 2 67 wl2 d x 105 for tji 560 joists δ 22 5 wl4 el 2 29 wl d x 105 material weights include tji weights in dead load calculations see design properties table at left for joist weights tji joists are intended for dry use applications.
Trus joist tji joists are made with no observable twist and have minimal material variation between joists within any joist series depth.
Unless you specify the 360 or 560 series tji joists and the span is not excessive open to debate or discussion the slenderness ratio for the 110 210 or 230 series is not much.
Tji joist benefits easily drilled and cut for plumbing and ductwork.
Our code report icc esr 1153 specifically states that bridging is not required for floor and roof tji joist applications.
You don t have to install the beam at midspan of the joists but the farther you go from midspan the less effective the beam becomes.
However bridging is one of the least effective solutions for bouncy floors.
Proper bridging distributes the load on the floor to other joists and over time prevents floors from sagging and squeaking do to floor joists twisting and warping.
Even if your floor already has a row of bridging running down the center you can stiffen it substantially by adding two more rows.
Floor joist bridging is critical to the structural strength of a floor as shown in figure 1.
Bridging allows each joist to share weight with its neighbors and can cut deflection how much the joists flex by half.
Tji joists are lightweight and come in long lengths which makes them faster and easier to install than traditional framing and saves you both time and money.
