| 摘 要： | 对带约束拉杆方形钢管混凝土轴压构件的力学机理进行分析,借鉴约束混凝土本构模型,基于等效侧向压应力的概念,提出适合带约束拉杆方形钢管混凝土柱数值计算的核心混凝土本构关系,并结合有关试验结果对本构关系中的参数进行确定。应用该本构关系对有关试件进行荷载-应变关系全过程计算,计算结果与试验结果比较,两者吻合良好。

| Abstract: | A constitutive relationship for square concrete-filled steel tube with binding bars (square CFT-WB) is put forward based on the analysis of interaction within the components of square CFT-WB and the conception of equivalent lateral compressive stress. The constitutive relationship takes a similar form of the constitutive model of confined concrete while its parameters are modified to fit square CFT-WB according to experimental results. Finally, a calculation of complete load-stress relationship curves is conducted for some certain experimental specimens using this constitutive relationship. The comparison between the results of calculation and the results of experiment shows that they agree well with each other. |
