reinforcing existing floor
(OP)
Working on a project where the existing TJI's are overstressed. I'm thinking about adding joists to reduce the tributary width problem is Ican't get any nails into the joist. I'm considering using an adhesive inlieu of the nails. Anybody know of a reference for construction adhesives that gives mechanical properties.

As for the original post, if there are new TJI's added between the existing, I would try to use a more positive attachment. One suggestion is to use a short Z-clip on each side of the TJI top flange with short screw up to the sheathing and nail to the TJI flange.

My initial concern is how to quantify the amount of shear the adhesive can take resist. However with the Z clip idea I think I can get a better feel with type of connection.

For the Z-clip, I'd use the length comparable to a Simpson A35 clip with two fasteners at each attach points, staggered each side of the TJI flange.
