要旨 This paper presents the results of an experimental program focusing on the axial compressive behavior of concrete columns reinforced by ultra-high-strength (UHS) rebars. In a total of eighteen columns (nine squares and nine circles) reinforced by UHS with the tensile strength over 1400 MPa were tested under axial compression, with stirrup spacing (4, 6, and 8 times of rebar diameter), the number of longitudinal rebars, and the concrete strength being the main variables. The test results are evaluated in terms of strength, strain ductility, and toughness index. The results indicate that comparing with the square columns, the circular columns have higher strength but with lower strain ductility and toughness index.
