- Abstract
This paper describes a computationally stable and efficient method of analysing the behaviour of a concrete framed structure at all stages of loading, including the load-ascending, overload stage and the post-ultimate, softening stage. Non-linear, inelastic material behaviour is taken into account, as well as geometric non-linearities. The method is stable, even in the unloading range of behaviour, because it simulates a deformation-controlled test, whereby the structure is subjected to controlled, progressively increasing deformation, rather than to increasing load. Although the method of analysis was developed as a research tool to investigate important problems such as non-ductile collapse and slenderness effects in frames, any unwanted features can be stripped from the method to allow 'rigorous' analysis to be carried out in accordance with the new SAA Concrete Structures Standard. Comparisons of simulated structural behaviour up to collapse with actual laboratory test results have been used to check the accuracy of the method. The approach has been used to study the collapse behaviour of a three storey, two-bay multi-storey building frame.
