One way is to use the "equivalent diameter" concept as explained in Sec 9.1 of Leeson's "Physical Design of Yagi Antennas".  If you decide to go that route the math is incorporated in the AutoEZ "Clamps" dialog:

A more complete explanation of how to use this dialog may be found in the first section of this page:

The "Clamps" dialog is included in the free demo version of AutoEZ.  You are more than welcome to use the free version to calculate the equivalent diameter(s) and then manually transfer the results to an EZNEC (.ez) model.
