You're going to need to give a whole bunch more background on what you're showing us, beyond the ten lines of computer output, if you expect to receive a reasonable answer.

It looks to me like they just mean "actual calculated stress", and are assuming that the applied stress is a buckling stress.
The equation numbers quoted match the AISC ASD steel code, 9th Edition, just column formulas.

hi TGS4, yes that is correct but we must know the fundamental..
