I would like to clarify the relationship of CAESAR II's wind shape factor and ASCE 7-10's equation 29.5-1. Wind shape factor was not mentioned in ASCE 7-10.

In Eq. 29.5-1, wind force is calculated as F = qz*G*Cf*A. While in CAESAR II, wind force is F = Peq*S*A when wind pressure vs elevation was defined. My understanding is qz = Peq, A = A, and G*Cf = S. Thus, wind shape factor is equal to the product of gust factor G and force coefficient Cf. Is it correct?

Also, CAESAR II's user guide recommendation for wind shape factor is between 0.5 to 0.7. But in ASCE 7-10's Figure 29.5-1, this could be greater than 0.7. Consider G=0.85 and Cf=1.2, then G*Cf = 1.02. Am I correct if I input this value as wind shape factor? Considering the project requires ASCE 7-10 for wind loading and wind pressure vs elevation was provided already.

You can make any math equivalence you want, however "G" gives some troubles.

For ASCE wind case, if you leave the frequency value blank, CAESAR II uses the ASCE default of 0.85 for the Gust Factor. In case you perform a Modal Analysis of the system and obtain that frequency value, the gust factor shall be calculated according to ASCE 7 equations. As I know, the computed gust factor is not reported by the software but for sure considered into calculations.
I mean when G=0.85 you can easily do the equivalence but not for more accurate calculations.
Also must be sure that the profile wind pressure vs elevation which was provided already, includes or not G and/or Cf factors.

About Cf value I have a post here:
