Abstract

An experimental investigation on aluminum hollow section tubes is presented in this paper. Axial compression tests were conducted to investigate the effect of depth to thickness ratio (D/t) and length to depth ratio (L/D) on the composite aluminum tubes which were filled with No Aggregate Concrete (NAC). The behavior, compatibility and strength limits were studied. An M50 grade of concrete was used. Tubes were 6063-T6 aluminum heat treated alloy extrusions with 214MPa yield strength. The depth to thickness ratio for the tubes ranged from 12 to 33.3. Length to depth ratio (L/D) varied from 3 to 10 to include all modes of failure. The columns strength vs. load axial shortening graphs were plotted and failure modes were presented. Results have shown that columns had high stiffness but still failed before reaching the expected ultimate load. Most of the columns have failed by a classical 45 degree shear and some failed by buckling.
