Abstract

An experimental investigation of concrete-filled aluminium Circular Hollow Section (CHS) stub columns is presented in this paper. A series of tests was conducted to investigate the effects of the geometric dimensions of the aluminium CHS and concrete strength on the behaviour and strength of concrete-filled aluminium CHS stub columns. The structural performance of the concrete-filled aluminium CHS stub columns was investigated using different concrete cylinder strengths of 40, 70 and 100 MPa. The CHS tubes were fabricated by extrusion using 6061-T6 heat-treated aluminium alloy having nominal 0.2% proof stress of 240 MPa. The diameter-to-thickness ratio of the CHS tubes ranged from 9.7 to 59.7. The column lengths were chosen so that the length-to-diameter ratio generally remained at a constant value of 3 to prevent overall column buckling. The concrete-filled aluminium CHS specimens were subjected to uniform axial compression. The column strengths, load-axial shortening relationship, load-axial strain relationship and failure modes of the columns were presented. The test strengths were compared with the design strengths calculated using the American specifications for aluminium and concrete structures. It is shown that the design strengths are generally conservative for concrete-filled aluminium CHS stub columns.
