| 摘 要： | 根据12根不同配箍特征值的T形柱进行轴心受压试验的数据,绘出T形柱的应力—应变全曲线,分析配箍特征值对T形截面柱强度和延性的影响。推导出约束混凝土的应力—应变全曲线,考察配箍特征值对约束混凝土应力-应变全曲线的影响,通过分析配箍特征值对T形柱约束混凝土强度的影响,得到适合于T形柱的配箍特征值的取值范围。

| Abstract: | The stress-strain curve for every T-section column is drawn,and volume reinforcement characteristic's effect to the strength and ductility of T-section columns is analyzed according to the uniaxial compression experimental data,which is based on 12 T-section columns of different volume reinforcement characteristics.The stress-strain curve for confined concrete is induced.Volume reinforcement characteristic's effect to the stress-strain curve for confined concrete is analyzed,and the fit variation scope of volume reinforcement characteristic is obtained by analyzing volume reinforcement characteristic's effect to the strength and ductility of T-section column. |
