摘要
各国规范中对钢管混凝土构件刚度的定义存在着很大差异,我国不同部门也各自有不同的规定,而钢管混凝土刚度取值的不同将对钢管混凝土桁式拱桥内力、变形和稳定等的计算结果产生影响。在一座钢管混凝土桁式拱桥实桥资料的基础上,分析了抗压刚度和抗弯刚度对桁式钢管混凝土拱桥静力计算的影响,并提出了一些建议。
There are many differences in the define of the rigidity for concrete filled steel tube（CFST） component between different countries. And also in our country different departments have their own standards which influence the calculation results of internal forces, deformations and stability etc. In this paper, the effect of flexural rigidity and compressive rigidity on static characteristics of CFST truss arch bridge was discussed based on a real bridge. The educed conclusions are believed to be useful for reference in design and construction.
