摘要:

在总结各国钢管结构研究现状的基础上,分析了部分填充混凝土钢管结构的类型及工程应用,探讨了部分填充混凝土钢管桁架结构桥梁的形式,展望了部分填充混凝土钢管桁架新型结构桥梁的优势和应用前景,最后以一座刚性悬索加劲的三跨连续钢桁梁桥为例进行了部分填充混凝土前后的静动力特性对比分析。结果表明:在钢桁梁桥弦杆内填混凝土能降低杆件的应力水平,提高桥梁的整体刚度。

Abstract:

A summary of existing researches on steel tubular structures was presented. Structural styles and engineering applications for partially concrete-filled steel tubular bridges were analyzed based on the above researches. Structural styles of partially concrete-filled steel tubular truss bridges were also analyzed. The prospects for the development on this novel kind of steel tubular truss bridges and their advantages were discussed. At last, static and dynamic characteristics of a continuous steel bridge stiffened with rigid cables were compared with that of the partially concrete-filled truss bridge. The results show that the stresses of chord members of partially concrete-filled steel truss bridge are decreased, while its integral stiffness is increased.
