The principal parameter that has been considered in the test program is theslenderness of the component plates.   The experiments did reveal the beneficial effect of the use of concrete infillon delaying the onset of local buckling and thereby the post-local buckling behaviour of the columns.  This set ofexperiments is part of an on-going program of research which has been conducted at the Universities of Wollongongand New South Wales over the last decade. Further research will include the consideration of these types of members as part of overall structural assemblages, as well as utilising these members under high temperature andcyclic loading conditions to simulate fire or blast loading conditions respectively.
