Triforce analyzer 2.2.229
Barrette Structural Distribution, Inc. is proud to announce its new version of TRIFORCE® Analyzer including these main changes:

1. New Building Codes :
We always make sure to be up to date on the latest Building Codes available; so here are the latest one added:
- 2012 OBC 2010 NBC
- 2012 OBC 2015 NBC
- ICC 2018 IBC/IRC code
2. Reinforcement optimization :
2.1. Point Load (front or back) on Girders
Part of the new updates is the reinforcement required for a Top Mount hanger on a TRIFORCE® girder. This new feature will save up to 2 plies of reinforcement! TRIFORCE® Analyzer will specify the reinforcement required according to the intensity of the load applied in the Top Mount hanger, without systematically adding the 3 thicknesses of reinforcement which are required for the nailing of a Face Mount hanger.
“Load Cause” will appear when front or back is selected under the “Applied to” section and when Concentrated load is selected under “Distribution” section.
Before analyzing a girder with a Top Mount hanger, you will will need to look at your “Lumber Filler Block Preference” under the “Preference” tab:
You will then be able to analyze your joist with your point load:
EXAMPLE WITH A TOP MOUNT HANGER
In this example, a single ply girder 2×3 OJ314 11 7/8” with a point load of 300 lb (using Top Mount hanger) at 4’-0’’ from the left only need 1 ply of reinforcement installed between the top and the bottom chord:
New reinforcement details are available to go along with your placement guides. Here are some examples:
SAME EXAMPLE, BUT WITH A FACE MOUNT HANGER THIS TIME
If you select Face Mount hanger, using the same example above (a single ply girder 2×3 OJ314 11 7/8” with a point load of 300 lbs. at 4’-0’’ from the left), it will need 1 ply of reinforcement installed between the top and the bottom chords and 2 plies to be installed over, meaning covering both the top and bottom chords for a total of 3 plies:
Reinforcement details are available to go along with your placement guides. Here are some examples:
2.2. Line Load / Concentrated Load on Top chord Without Reinforcement
Another update is no reinforcement required on certain condition for top line load.
When applying line loads on the top of the joist (ex: perpendicular bearing wall setting on top of the floor like in attic rooms or column on top), depending on the size of the load (width) and on its location, you may no longer need reinforcement if the line load sits on the junction of the diagonals and the top chord.
EXAMPLE WITH A TOP LINE LOAD
In this example, a single ply joist 2×3 OJ314 14” space at 16” o.c. with a concentrated load of 300 lbs. add to the top at 5’-2’’ from the left:
With this update, TRIFORCE® Analyzer optimizes the load transfer trough the webs going downward the bottom chord more efficiently than ever.
So, no specific detail is needed, simply send the joist design to costumers.
For the same loads but, this time, where the loads would set between 2 junctions:
In that case, TRIFORCE® Analyzer will reinforce the joist to transfer the loads from the top to the bottom chord.
***N.B. Using top mount hanger for a header is not consider as a load applied to the top***
2.3. Cantilevered joists Without Reinforcement
Another part of the updates is no reinforcement required on certain condition for cantilevered joists.
When bearing the joist on the junctions of diagonals and the bottom chord, depending on the size of the loads (width), you may not need any reinforcement.
EXAMPLE WITH A BEARING ON A JUNCTION:
In this example, a single ply joist 2×3 OJ314 14” space at 16” o.c. with a line load of 300 lbs. from the left with a 2 feet cantilever:
No reinforcement would be needed:
Since no reinforcement is required, simply send the designs without any particular framing detail.
EXAMPLE WITH A BEARING NOT ON A JUNCTION:
Using same example above, a single ply joist 2×3 OJ314 14” space at 16” o.c. with a line load of 300 lbs. from the left, but with a 1 feet cantilever:
In this case, TRIFORCE® Analyzer will reinforce both sides in order to help the bottom to transfer loads trough the joist.
Once again, TRIFORCE® Analyzer will optimize the reinforcement in order to have the smallest pieces as possible.
You can use detail 8V2(reinforcement from the end of joist) or 8VS (reinforcement centered on bearing)
In all cases, it is important to transfer the right information to costumers in order to make sure that joists are installed as per your design and with the right reinforcement (or not).
Hint: For best result, try as much as possible to have your reinforcement set as Vertical Orientation in your Reinforcement Preference:
