摘要
鱼腹式箱梁边腹板倾斜,截面变化大,受力分析复杂。文中以(28+40+28)m现浇鱼腹式箱梁为研究对象,采用折面梁格法进行受力特性分析计算,并与单梁模型的计算结果进行对比分析研究,总结了不同荷载工况下结构计算结果的异同,为鱼腹式箱梁结构精细化分析计算提供思路,使计算结果与工程实际情况相符。
The side web of fish-bellied box girder is inclined,the section changes greatly,and the force analysis is complicated.In this paper,(28+40+28)m cast-in situ fish-bellied box girder is taken as the research object,and the folded-beam grillage model is used to analyze and calculate the mechanical characteristics,and the calculation results of the single beam model are compared and analyzed,and the similarities and differences of the structural calculation results under different load conditions are summarized,which provides ideas for the fine analysis and calculation of the fish-bellied box girder structure,so that the calculation results can be consistent with the actual engineering situation.
