| 摘 要： | 进行了8个冷弯型钢钢管混凝土构件的试验,表明其具有良好的力学性能。在确定组成矩形冷弯型钢钢管混凝土的钢材和核心混凝土应力-应变关系模型的基础上,利用数值解法对其轴压、纯弯和压弯构件的荷载-变形关系进行了全过程分析,分析结果与试验结果吻合良好。最后在参数分析的基础上,提供了轴压、纯弯和压弯构件承载力的实用计算方法。

| Abstract: | Tests on eight rectangular concrete-filled cold-formed steel tubular specimens were carried out. The stress-strain relations for steel and concrete are established. A theoretical model is developed in this paper for the composite stub columns, beams and beam-columns. A reasonable good agreement is observed between the predicted and tested curves. Based on parametric analysis, simplified calculation methods are derived to predict the load-carrying capacities of the composite members. |
