摘要
从方钢管混凝土柱的约束特点出发,将核心混凝土划分为强约束区和弱约束区,类比配置螺旋箍筋的钢筋混凝土柱计算公式,推导出方钢管混凝土柱的承载力公式,并与已有试验结果进行比较,对比结果表明,计算值与试验值吻合较好。
Based on the restraint characteristic of concrete-filled steel square tubular （ CFST） column, core concrete area is divided into the strong restraint area and the weak restraint area .A formula is derived for estimating the bearing capacity of square CFST column by analogy RC column with spiral stirrup .The proposed formula is compared with the experiment results ,the computing results of square CFST column formula agree well with the experimental results .
