Open Joist Triforce Wood Joists

[smb_PE]

I'm working on a project where the owner/developer wants to use the Barrette open joist triforce wood trusses:

In concept, the triforce trusses are intriguing because one end has a solid OSB section (like a wood I-joist), enabling the framers to field trim as necessary. Also, the web to chord connections are finger-jointed and glued.

I've worked with metal plate connected trusses before on mixed-use multi-story wood jobs where the trusses were delegated design. However, I'm approaching the triforce system as I would a wood I-joist system.

Has anyone used this or similar joists before? Anything I should watch out for when designing this system?

Looks like a Canadian product. If it is a US project, you should check to see if it has ICBO approvals.

I remember about 40 years ago, my timber Professor was doing research/testing of similar finger jointed trusses.

barrettes tri force is a good product.
quite a few of my projects have been done using their system.
it is a manufactured product and does have ccmc approval.
on all my projects i delegate the floor system to the manufacturer. i just put floor joists by manufacturer.
i do this for the joists and trusses only.
all other beams girders etc are designed and indicated on my drawings.
one thing i did notice from barrette is that they dont always use the correct bearing materials and i specify that shop dwgs are to be sent for review and approval prior to fabrication.
what area are you in. i may be able to help you more navigating their system.
