Compression tests on stub columns were performed on a range of 13 groups of specimens. A reliability analysis was undertaken on the test results with respect to the calculation methods of AS/NZS 4600. It was found that the current method of applying the lower web yield stress in the entire section is conservative. Applying the separate flange and web yield stress to the individual components produces higher capacities by approximately 15%, within an acceptable level of reliability. Finite element analyses were carried out to compare the results of numerical simulation with test results and demonstrated a close prediction of the test ultimate load despite some discrepancies were observed.
