Abstract

The main target of this study is to investigate the behavior and performance of long composite circular stainless steel columns filled with light-weight concrete. An experimental study was carried out on four specimens, two of them are long composite circular stainless steel columns with length 1400 mm, diameter 100 mm and thickness of stainless steel tube 2 mm filled with light-weight and normal concrete with strengths 12 and 26 mpa respectively, which denoted by C1400/12 and C1400/26. The other two specimens are short composite circular stainless steel columns with length 500 mm, diameter 100 mm and thickness of stainless steel tube 2 mm filled with light-weight and normal concrete with strength 12 and 26 mpa respectively, which denoted by C500/12 and C500/26. The ultimate load, failure mode and axial shortening have been investigated. Failure of long column was due to flexural buckling of stainless steel tube and due to local buckling of it for short columns. For L/D was 14 using light weight concrete in stainless steel composite long columns decrease the capacity of the column to nearly 47% than normal concrete. Capacity of long composite column (L/D=14) with light weight concrete is nearly 85% of short composite column (L/D=5)with light weight concrete.
