High strength steel is gaining more attention from engineers due to its high strength-to-weight ratio and cost effectiveness. However, the research on cold-formed high strength steel (CFHSS) tubular members subjected to combined compression and bending is limited. This paper, therefore, presents an experimental investigation on this combined loading scenario. The test specimens consisted of 5 square hollow section sizes and 2 rectangular hollow section sizes. The nominal proof stresses of the test specimens were between 700 MPa to 900 MPa. A total of 51 short beam-columns were tested to investigate the behavior of CFHSS rectangular and square hollow sections subjected to combined compression and bending. A set of different initial loading eccentricities were adopted to attain a wide range of bending-to-compression ratios. The compression and bending capacities, load-deformation histories and failure modes of the test specimens were reported. Based on the test results, the design methods described in American, Australian and European codes were evaluated. The finite-element modelling methodology for CFHSS tubular beam-columns was also presented.
