Dear Bentley,
For the attached sample moment connection, we have found that limcon is resulting hire moment capacity of bolt group while comparing the same as per the AISC code (refer to comparison in page No. 2 & code reference in page No. 3).
Please provide Limcon reference procedure for calculating the bolt group moment capacity.

We are not really supporting Limcon any more as it is being replaced with Ram Connection, but if you send me the input file you are using I can take a look.
Please find attached limcon file
P05.lmc
Thanks, I ran your file in Limcon and I set up a similar file in Ram Connection. In both programs, as you noted, the program is using the distances from the compression flange to the bolt centroid as the moment arms in calculating the moment strength. Application of AISC 360-10 page 7-12 "Case II' is not done as far as I can tell. The code presents this as an optional, more conservative, method as I read it.
