| 摘 要： | 各国规范中对钢管混凝土构件刚度的定义存在着差异,因此钢管混凝土截面设计刚度取值的不同将对钢管混凝土哑铃形拱内力、变形和稳定等的计算结果产生影响.本文以一座钢管混凝土哑铃形拱桥的实测资料为基础,通过对目前钢管混凝土截面刚度计算方法的比较分析,对钢管混凝土哑铃形拱桥拱肋设计刚度取值提出了一些建议,可供工程实践参考.

| Abstract: | There are some differences in the define of the rigidity of CFST component between the codes of countries it influence the calculation result of internal forces,deformations,stability and self-frequency of CFST dumbbell-rib arch bridge in design.Based on testing results of a real CFST dumbbell-rib arch bridge,the comparative analysis by using different rigidity defines of the CFST component was carried out in this paper.Some useful conclusions were deduced to be help for the design of this type bridges. |
