| 摘 要： | 对普通箍筋轴心受压柱进行非线性分析时,由于混凝土的应力-应变曲线有下降段,当混凝土先达峰值应力后进入下降段,而钢筋尚未屈服,钢筋和混凝土不能同时达到各自的极限承载力,柱的承载力不能由两种材料的承载力简单叠加。密排环箍轴心受压柱是典型的常规三轴受压,可用三轴强度准则进行计算,计算结果偏于保守。

| Abstract: | In the nonlinear analysis of the axial compression column with plain stirrups,since the stress-strain curve of concrete has the drop section,concrete and steel can not reach the top stress at the same time,and the ultimate capacity of the column isn't the superposition of the two materials.The dense row ring stirrups column under axial compression is in the status of conventional 3-daxial compression stress,and the compression strength of it can be calculated with 3-daxial strength norms.The calculation result is conservative. |

| Keywords: | axial compression column constitutive model uniaxial strength 3-daxial strength ultimate capacity |
