摘要
本文通过模型实验和有限差分法电算,对桥跨结构主梁剪力横向分布进行了研究。由于采用板肋组合结构的力学模型和梁式边界条件,得出了较为正确的剪力分布。最后,根据电算及解析推理,提出了简支桥跨主梁剪力荷载横向分布的三种实用公式。
In this paper, the shear transverse distribution on the beams of bridge is researched using data of model tests and computation in the finite difference method. Because not only the mechanical model of the combined plate-rib structure, but also the boundary conditions of the beams type is taken into account, a more precise shear transverse distribution is obtained. Finally three simple formulae are given to calculate the shear transverse distribution in the finite difference method and analysis.
