Behaviour of concrete-filled steel tubular stub columns subjected to axially local compression
AbstractThe behaviour of concrete-filled steel tubular (CFST) stub columns subjected to axially local compression was experimentally investigated in this paper. A total of thirty-two specimens were tested. The main parameters varied in the tests are: (1) sectional types: circular and square; (2) local compression area ratio (concrete cross-sectional area to local compression area): 1.44 and 16; and (3) thickness of the endplate: from 2 to 12 mm. A finite element analysis modelling was used for the analysis of CFST stub columns subjected to axially local compression, and a comparison of results calculated using this modelling shows generally good agreement with the test results. The theoretical modelling was then used to investigate the mechanism of the composite columns subjected to axially local compression.
