While designing single angle per IS code in STAAD pro software, the output report shows design based on principle axis for which the angle design qualifies. However when the same design is performed in STAAD per AISC 360-10 code, the output report shows design based on geometric axis for which the angle design does not qualify. Please clarify if geometric design needs to be considered for AISC/IS codes and why the STAAD design report based on IS code does not design as per geometric axis and designs only considering principle axis.
