BEHAVIOR OF HIGH-STRENGTH CONCRETE COLUMNS UNDER CYCLIC FLEXURE AND CONSTANT AXIAL LOAD

In this study, six large-scale columns made of high-strength concrete (HSC) were subjected to constant axial loads corresponding to target values of 15%, 25%, and 40% of the column axial-load capacity and a cyclic horizontal load-inducing reversed bending moment. Results reveal that tie spacing, and therefore tie volumetric ratio and axial-load level, have significant effects on the flexural behavior of HSC columns. The need to include the axial-load level in code requirements for confinement reinforcement is pointed out.
