Square concrete filled steel hollow columns

ABSTRACT: Twelve square concrete-filled steel tubes (CFSTs) of three different section sizes are subjected
to axial compression. The lengths of each section size tested are 1.0 m, 1.5 m, 2.0 m and 2.5 m. These lengths
provide a range of columns, from relatively short to slender composite columns. The compressive resistance of
the composite columns are compared with the design strengths predicted by the South African standard (SANS
10162-1), as well as the European design standard (Eurocode ...
