On your first question skew correction factor is applied for the entire beam .

On your second question :
CN uses the section flange thickness for ts.

There are several conditions for applying the Skew correction Factor and it would be better to see what is applied for the specific case.
So please email me the Conspan file you are working on so that it will help us in our investigation.

One more question regarding skew: Can you describe how Conspan uses the equation in Table 4.6.2.2.3c-1 when the girder does not have a composite topping? In other words, t = 0. Thank you.

Vinay, I attempted to upload the relevant section from AASHTO 4.6.2.2.3c. To quote AASHTO, "The shear correction factors should be applied between the point of support at the obtuse corner and mid-span, and may be decreased linearly to a value of 1.0 at midspan, regardless of end condition." I am using AASHTO 2014, perhaps that is the problem? I reviewed AASHTO 2012 and see that this SENTENCE IS NOT IN THE 2012 CODE. I think we've found our problem! CONSPAN is using an older code, which does not have this provision.

However, I would still like to confirm that CONSPAN is using the skew correction factors calculated per the table 4.6.2.2.3c-1, rather than modelling the skewed support. Can you please confirm? Thanks.

I checked the AASHTO LRFD 4.6.2.2.3.c. article to see if there is any information related to skew correction factor that needs to be reduced along the beam.
Since i did not see any information related to varying the reduction factor , Please do point out at the comment in AASHTO.

I am confused by this answer. In the CONSPAN help section, it states that CONSPAN uses the reduction factors from AASHTO LRFD 4.6.2.2.3.c. The answer above states that CONSPAN models true skew supports. Which is it? Also, according to AASHTO LRFD 4.6.2.2.3c, the skew reduction factor varies from max at end supports to 1.0 at center. Is CONSPAN varying the factor per AASHTO?
