With the exception of the AISC 360-16 and AISC 360-10 steel design code, the AISC 341-05 code check will always use the AISC 360-05 steel design code to perform any member design capacity calculations, irrespective of the selected code in the Steel Standard Provision mode. That is, if AISC LRFD 3^rd is selected in Standard mode but AISC 341-05 LRFD is the selected code in Seismic Mode code, then all member capacities will be calculated using AISC 360-05 LRFD, not AISC LRFD 3^rd. Conversely, when AISC 360-10 or AISC 360-16 LRFD is selected in the Standard mode but AISC 341-05 LRFD is selected in Seismic Mode code, then all member capacities will be calculated using AISC 360-10 or AISC 360-16 LRFD respectively.

A few individual checks are not performed. When a check is necessary and is not performed by the program it will be indicated in the output.

It is recommended that P-Delta be performed in lieu of using B2 when performing an AISC 341 design check.
