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 self-compacting concrete (SCC). The behavior, compatibility and strength limits were studied. An M25 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 column strength vs. load axial shortening graphs were plotted and failure modes were presented. Results have shown that combination of selfcompacting concrete and Aluminum tubes is a good choice for construction and can withstand a considerable amount of load.
