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。
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 stressstrain 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.
