ABSTRACT
The present study is an attempt to study the possibility of using thin-walled HSS columns filled with SCC. New test data on thirty-eight HSS columns filled with SCC to investigate the influence of concrete compaction methods on the member capacities of the composite columns are reported. The specimen tests allowed for the different conditions likely to arise in the manufacture of concrete: cured, well compacted with a poker vibrator, well compacted by hand, and self-consolidating without any vibration. The main parameters varied in the tests are: (1) column section types, circular and square, (2) tube diameter (or depth) to thickness ratio, from 33 to 67, and (3) load eccentricity ratio (e/r), from 0 mm to 0.3. Comparisons are made with predicted column strengths using the existing codes such as LRFD-AISC-1994, AIJ-1997, BS5400-1979, EC4-1994 and DBJ13-51-2003(2003).
