TJI joists
(OP)
I'm using the following resource (http://www.techsupport.weyerhaeuser.com/hc/en-us/a...-) to check some TJI joists with point loads. The only problem: this manufacturer's "span tables" are all heavily based on uniform loads. Also they don't really show how the capacities are derived for these uniform loads. How does one determine capacities and deflections for these properietary joists with loading beyond the scope of the span tables, including point loads?

You can't use NDS for these things. Open up your NDS book (2013 edition) page 50.
"Reference design values for prefabricated wood I-joists shall be obtained from prefabricated I-joist manufacturer's literature or code evaluation reports"

I'm sure you could use an equivalent uniform load that reproduces your max moment and max shear and then compare to the table.
