| 摘 要： | 本文分析了40根离心螺旋筋管混凝土短柱的偏心受压实验结果.实验取螺筋间距和偏心距两种指标作为主要参数.实验结果表明,该种短柱的破坏可分为大、小偏压两种破坏形态.在纯弯时不计"套箍"强化的基础上得到了大、小偏压承载力公式.计算结果与实验结果吻合较好.

| Abstract: | In this paper 40 short concrete filled tubular columns with spiral reinforcement under compression loads with different eccentricities are analysed. The pitch of spiral reinforcement and eccentricity were considered as the two chief parameters in test. Experiments show that there may be two types of failure in the tested short columns, one with large eccentricities and the other with small eccentricities. The limit eccentricity and the calculation formulae of ultimate strength of columns with bigger and smaller eccentricities are derived on the basis of neglecting the confinement effectiveness under pure bending condition. Calculated results are in good agreement with the experimental data. |
