I-Joist Rafter Details Question.

[XR250]

As much as I dislike I-joists, I am stuck with them on this job. Looking for some feedback on this detail...

1) Does the connection between the double rafters seem reasonable? Not a lot of ply to ply load here, just a monster 28' span.

2) For the connection to the top plate, does anyone know how much uplift I can get out of the i-joist before the bottom flange fails?

3) For the perimeter band, does it seem reasonable to nail into the end of the flanges or should I use a filler block?

I have not shown the blocking between the joists over the wall.

Thanks!

The connection does NOT seem reasonable to me but only because I thought that when load was applied from the side (and not from directly above) it was necessary to connect two I joists with web fillers (NOT thru the flanges).
Refer to the attached detail from one of the I joist makers.
