| 摘 要： | 通过分析40根长细比为168至228的偏压试件试验结果,提出了环形截面预应力混凝土偏心受压细长柱的承载力计算公式。在这些公式中考虑了长细比、偏心率及预应力对承载力的影响。计算结果与试验结果对比表明,两者吻合良好。

| Abstract: | By analysing the test results of forty P R C columns with the slenderness ratio from 168 to 228 under eccentric compressive loading,the formulas for cuculating the bearing capacity of slender P R C Columns with ring cross sections are presented for eccentric compression The effects of the slenderness ratio,eccentriccity ratio and prestress of concrete upon the bearing capacity are taken into account The theoretical results calculated by the proposed formulas are in good agreement with the experimental datum |
