Ductile Properties of High-Strength Concrete Columns with Spiral Reinforcement |
| Abstract |
Various studies have been done to investigate the effectiveness of lateral confinement of lower strength concrete(below 420kg/cm2). But little research anounced its effectiveness for high strength concrete. A certain concern has been arised that the beneficial effect of lateral confinement in high strength concrete may be different from that in lower strength This study aimed to investigate that concern with different confinement spacing(D/2:D/4). The results show that beneficial effects of spiral confinement are more pronounced for lower strength concrete as compared to higher strength concrete. |
