Abstract | ABSTRACT: The aims of this study are to generate experimental data on aluminium alloy continuous beams
of square and rectangular hollow section (SHS and RHS) with internal stiffeners, as well as to assess the current
design approaches for indeterminate structures using this new cross-section shape. The experimental programme
comprised material tests and five-point bending tests (i.e. continuous beams over three supports) with three
different loading configurations. Generally, the specimens failed by the formation of a collapse mechanism
comprising three plastic hinges. Comparisons of the test results with design strengths were also carried out.
The design strengths predicted by the American (2010), Australian/New Zealand(1997) and European (2007)
specifications are found to be rather conservative. The plastic hinge method in Annex H of Eurocode 9 (2007)
provides improved results, while the Continuous Strength Method (CSM) for indeterminate structures gives the
most accurate and consistent predictions. The results reveal that both strain hardening at the cross-sectional level
and moment redistribution at the global system level have significant influence on the structural performance
of stocky aluminium alloy structures. |
