Circular High-Strength Concrete Columns under Concentric Compression

摘要

Circular columns with concrete strengths in the range of 60 to 124 MPa (8.7 to 18.0 ksi) were tested under concentric compression. The Columns were confined with different volumetric ratios, grades, and Spacings of circular reinforcement. Test included both poorly ocn- Fined and well-confined columns. Th results provided insight into The strength and deformability of circular high-strength concrete (HSC) columns and were used to generate design information for confinement of these columns.
