| 摘 要： | 采用桁架－拱模型，利用平衡条件，协调条件和砼软化应力，应变关系以及钢筋的应力－应变关系，对钢筋砼框架短柱剪强度进行了分析，并利用该方法对国内所做６３个普通砼框架短柱的试验结果进行了强度分析，计算结果与试验结果符合较好。在此基础上，利用陶粒砼的软化应力－应变关系，对作者进行的９根钢筋高强陶粒砼框架短柱试验结果分析，亦取得了较好的效果。

| Abstract: | In this paper, based on equilibrium and compatibility conditions, as well as the softened stress strain relationship for concrete and elastic perfectly plastic stress strain relationship of mild reinforcing steel, the strength of reinforced concrete columns under combined axial, bending and shear forces was evaluated using the beam arch mechanism. The theoretical predictions obtained here was compared with the results of tests of 63 column spcimens and 9 light weight aggregate column specimens in our country and a satisfactory agreement was found. |
