Seminar - Frank Zhu - Stub column behaviour of LiteSteel Beams
Wednesday 16 August 2006, 1.10 - 1.50 pm
Civil Engineering Lecture Theatre 3
The presentation introduces an investigation into the strength of stub columns of hollow flange channel (LiteSteel Beam) sections manufactured by Smorgon Steel Tube Mills. Compression tests on stub columns were performed in the range of 13 groups of specimens. A reliability analysis was undertaken on the test results with respect of 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 30%, an acceptable level of reliability.
