| 摘 要： | 为解决工程中得到广泛应用的钢管混凝土结构承载力计算问题,在总结分析已有钢管混凝土短柱承载力计算理论的基础上,利用弹性变形理论,推导出了钢管混凝土短柱极限承载力计算公式,利用推导得出的计算公式,对混凝土的泊松比趋近于零、混凝土的弹性模量趋近于零、钢管和混凝土的弹性模量和泊松比都相等、钢管和混凝土的泊松比相等而其弹性模量不等、钢管混凝土短柱端面上混凝土凸出或凹进的影响等六种条件下,钢管混凝土结构的承载情况进行了分析.

| Abstract: | In order to solve the calculation problem of the concrete-filled steel tube in project application,the computational formula of ultimate bearing capacity for the short concrete-filled steel tube pile was deduced on the basis of summarizing and analyzing the existing computational theory base on the elastic deformation theory.Then,using the formula deduced,the bearing capacity for the short concrete-filled steel tube pile was analyzed as the following six conditions:the poisson ratio of concrete is close to ... |
