| 摘 要： | 针对箍筋约束与碳纤维约束混凝土轴心受压力学性能，基于大量的轴心受压试验数据，分析了约束混凝土轴心受压力学性能的主要影响因素，分别建立了箍筋约束与碳纤维约束混凝土轴心受压时的峰值应力、峰值应变和极限应变的计算公式；对比分析结果表明，箍筋约束混凝土优势在于低特征值段，碳纤维约束混凝土的性能在高特征值时将超过箍筋约束混凝土。

| Abstract: | Aiming at confined concrete with stirrups and carbon fiber reinforced plastic(CFRP) respectively, the major influence factors of mechanical behavior of confined concrete under axial compression were studied based on reported experimental data. The equations for calculating the peak stress, peak strain and ultimate strain were proposed respectively for confined concrete with stirrups and CFRP. Contrastive analysis shows that the behavior of confined concrete with stirrups is better than confined concrete with CFRP in low characteristic value, whereas the conclusion is contrary in high characteristic value. |
