Floor Wood Truss Capacity
Floor Wood Truss Capacity
(OP)
Hello all -
We are trying to evaluate existing floor wood trusses. The contractor wants to hang some mechanical equipment.
Is there a place where I could find the capacity of these trusses? We have double cords, 20" deep and span 27feet in commercial. Or do I have to run the numbers?
Thanks in advanced!

Often is may be easier to analyze the truss for the existing load, and then new, and then check each place where the loads have increased. You may end up needing to plywood the joints to feel confident in the load spread.
Depending on the weight of the mechanical, you may just be able to install some stiff strongbacks to spread the load across multiple trusses.

I thought it might be something something similar to SJI tables. I guess not.
Does the TPI have tables for the plates?

Found it, he posted a link to the TPI 2014 document in this thread.

I haven't looked at it, so I can't comment whether it's actually what you're after.
