摘要
各国规范中对钢管混凝土构件截面刚度的定义存在着差异,钢管混凝土截面刚度的取值对钢管混凝土拱内力、变形和稳定计算均有影响。本文以1座实桥的实测资料为基础,对现有钢管混凝土截面刚度的不同算法进行了比较分析,得出了一些有益的结论,可供工程实践参考。
There are some differences in the definition of the rigidity of CFST component between the codes of different countries.These differences influence the internal force,deform,stability of CFST arch.Comparing with the results of the testing of a real bridge,the calculation for it by using the different rigidity definitions of the CFST component was carried out in this paper.Some useful conclusions were deduced and it will be of help for the design of this kind of bridge.
