    Abstract

    This paper reports nine test results of concrete filled steel tube reinforced concrete (CFSTRC) columns, which were tested under constant axial load and cyclically increasing flexural loading. The main parameters varied in the experiments were axial load level and cross-sectional type. The influence of these parameters on strength, ductility, stiffness and energy dissipation was investigated. It was found that, in general, CFSTRC columns exhibit favourable energy dissipation and ductility, even when the columns were subjected to high axial loads. This type of composite column is adoptable in practical engineering, particularly in regions of high seismicity.
