| 摘 要： | 通过13根箍筋约束混凝土T形截面短柱的轴心受压试验，研究箍筋约束混凝土T形截面短柱的轴心受压承载力。分析了轴心受压下T形截面柱箍筋约束混凝土的强度随配箍特征值、箍筋有效约束系数的变化规律，结果表明T形截面柱箍筋约束混凝土的抗压强度随配箍特征值、箍筋有效约束系数呈非线性关系。根据分析结果建立了箍筋约束混凝土T形截面短柱轴心受压承载力计算公式，与试验结果比较，计算公式偏于安全，可用于箍筋约束混凝土T形截面短柱轴心受压承载力的分析。

| Abstract: | Bearing capacity of axially loaded T-shaped columns confined with stirrups was studied on the basis of the tests of 13 T-shaped columns under axial load.It was analyzed how did the compressive strength of confined concrete change with the stirrup characteristic values and the stirrup effective restraint coefficient.It is indicated that the compressive strength of confined concrete presents a nonlinear relationship with the stirrup characteristic values and the stirrup effective restraint coefficient from th... |
