Solar panels - TJI Rafters - Uplift??

[mtlogcabin]

Here is a link to loading the bottom tji flanges. The withdrawl loads will work for uplift on the top cords. It is the diameter and depth of threads you need to be concerned with. Also note the installer needs to be pre-drilling the holes for the fasteners. This is just I-levels literature you should be able to get the same info from whoever manufactured the I-Joist that is installed.

I called the technical department for Trus-Joist and explained the situation.Rep stated the chord-to-web connection is rated for 500 lbs at any point.

That is the point that the chord to web connection will fail

I just happened to notice the thread was updated. Strange, there must be some option for email notification when a thread is updated.

Anyway, the pre-drilling was discussed and required. I also noted that they were furnishing all the hold-down with 1 lag screw, whereas the mounting "feet" are secured with two lags. They were able to make the lags smaller by dividing the load between two.

I appreciate all the help!
