When carrying out a code check to AISC 360-10 using STAAD Pro V8i SS5 (20.07.10.41), the 2nd, 3rd and 4th members in my member list are consistently omitted from the code check. The member first in the list displays a UR and this also appears on the unity check diagram but the 2nd, 3rd and 4th members are "N/A" in the list and appear grey on the screen (not green). This happens on more than one similar type of model (lifting frame analyses). I've tried renumbering the members but the same thing happens and whatever members are 2nd, 3rd and 4th in the list do not get code checked.
I seem to be able to "trick" the program by renumbering the members tactically and putting my 'dummy' members as the first few in the numbered list but this seems a bit messy just to get the code check to consider all my relevant members.
Can anyone advise what may be happening here and if this is a bug or more of a 'user error'! ?
Thanks. Nick
Thanks. I don't have access to that build software. See model attached.
