Flexural Behavior of High-Workability Concrete Columns Under Cyclic Loading

This article reports on a study undertaken to investigate the behavior of high-workability concrete (HWC) columns under cyclic loading. Ten of the 20 columns in the study were made with HWC, and the rest were made with normal-workability concrete. The test variables included the concrete strength, level of axial force, strength of transverse reinforcement, and spacing of transverse reinforcement. The specimens were tested under constant axial force and cyclic transverse load. Comparisons were made between HWC columns and normal concrete columns. The authors discuss flexural strength, ductility, energy dissipation, and crack width. The results show that HWC columns have better ductility and energy absorption capability than normal concrete columns. In addition, the crack widths of HWC columns are smaller than those of normal concrete columns. The authors conclude that HWC can be used to improve the concrete quality and the member behavior, and may to some extent reduce the steel congestion problem.
