   Depends on where you are--Corpus not Uvalde not Alpins not Temple not Tyler; all have humidity, just in different ways.

   I've never thought of using a TJI for a carport.  Makes me want to go the GP site and see if they say anything about exposure.

   Now, I'm guessing you are trying for a 24' span, rather than, say, parallel 12' x 24' bays. 

   The reason I bring this up is not the depth or construction of the 24' "joists" but the depth of the beam those will sit upon.  That beam will cut into the headroom at either side of the carport right where it is wanted most (or force you to add more height than is needed).

   How are you planning to handle roof pitch?  Tip to one side or the other?  What roof are you considering?  Need the location to know if you need to consider uplift from wind (and/or storms).

   These sorts of things are precisely why may carports wind up built from steel sections welded together.  The nice, open, spans and dimensions are also handy for decreasing potential yellowjacket neting areas, too.

   Steel ibeams are somewhat cheaper material, but can often be more expensive labor wise to work with.

   So I would order them predrilled to fasten PT plates to the top flange, and set them up on the piers. ( Not sure what it takes in TX to do appropriate holddowns for Tornadoes) Then run all the floor joists and rim over top of them, toenailing into the PT Plates.

   that's an I Beam.

   I don't much care for working with steel either.   View Image                                          View Image

    I beams (steel)? or I joists (wood)?  There seems to be some confusion here.  And there's a big difference!

   Make sure what ever you use is rated for Exterior use. A lot of gluelams also need to be protected from UV rays etc.
