| 摘 要： | 基于最小势能原理计算方钢管混凝土柱的界面滑移位移。建立方钢管混凝土柱的拉拔力学模型,利用最小势能原理在锚固长度方向建立方钢管与混凝土界面的相对滑移计算公式,求解出型钢混凝土界面的相对滑移并进行了数值计算与分析,与有关文献试验结论基本一致。方钢管与混凝土界面的相对滑移具有二次曲线分布的基本特征。研究成果可以用来描述型钢混凝土界面的相对滑移规律,对于完善钢管混凝土设计理论及进一步研究粘结-滑移本构关系具有一定意义。

| Abstract: | Based on the principle of minimum potential energy,the interface slips in concrete filled square steel tubular column is calculated.According to the study of bond-slip behaviors of steel reinforced concrete and steel tube concrete,a pull-out mechanics model of concrete filled square steel tubular column is built.The slip displacement on the interface of steel and concrete of the column along the embedment length is derived by the principle of minimum potential energy.The calculation results show that the sl... |
