If you have access to the June 1998 issue of IEEE Transactions on
Broadcasting, check out the article:  "A Method for Modeling Array Elements
When Using NEC and MININEC" by J.L. Smith.  The author discusses methods
for modeling towers and in particular, describes a single-wire
representation for a triangular cross section tower.  His result is that
the radius of the equivalent wire equals the cube root of the quantity
(D*F^2)/2 where D is the diameter of each tower leg and F is the width of
the tower face with all dimensions in the same units.  Some references are
cited to justify this result.
