"uplift" is lift on a surface due to air pressure (like wind).

a strut with a component normal to this surface will react this load. Could be termed "drag strut", but that has a specialised meaning (typically reacting drag forces like on a landing gear or a wing).

another day in paradise, or is paradise one day closer ?
 
So it would resist uplift but I cannot rely on it and use in my calcs for uplift?
 
In the parlance of modern building design for lateral loads, the term "drag strut" usually denotes a predominantly axially loaded horizontal member installed within a floor or roof framing system. They are not normally members used to resist significant uplift. That said, any member can be designed to do any thing so long as you've tended to the design and detailing properly. Why don't you tell us a bit more about what this member is and what you need it to do within your structure? As always, a picture is worth 1000 words.
