摘要
建立八边形钢管混凝土轴压短柱的有限元模型,并基于现有的试验数据验证了该模型的正确性.利用该模型分析应力、应变和约束力的分布规律.基于72个典型算例和现有的简化公式,提出八边形钢管混凝土轴压短柱的强度设计公式.
A finite element （FE） model is achieved for octagonal CFST stub columns. The FE model is verified by existing experimental data as well. Based on this FE model, the distribution of the stress, the strain and the confinement pressure on concrete is analyzed. At last, a simplified calculat- ing formula is recommended for the strength design of octagonal CFST stub columns according to FE predicted results of 72 typical samples and existing simplified calculating formulas
