基于模态分析的鄄城黄河公路大桥优化设计

Optimization Design of the Yellow River Main Bridge in Juancheng Based on the Researches on the Dynamic Characteristics

波形钢腹板箱形梁桥是一种较为新颖的桥梁结构形式.从结构的动力特性研究入手,通过改变不同结构断面形式、设置不同数量内横隔板,对结构动力特性的差异进行了比较分析,为鄄城黄河公路大桥的优化设计工作提供了技术支持,也为其它工程的设计提供了借鉴.

The box girder with corrugated steel webs is a kind of new type of the bridge structure.On basis of figuring out the dynamic characteristics of the structure,this paper provides some creative work to seek the characteristics of this kind of structure by comparing the different dynamic characteristics with changeable sections and different numbers of inner diaphragms,which is helpful to the optimization design of the Yellow River main bridge in Juancheng.
