长联大跨曲线梁桥空间受力分析

Analysis on Spatial Force of Long-span Curved Girder Bridge

摘要:

利用通用有限元软件Midas/Civil建立有限元模型，对1座长联大跨曲线梁桥结构进行空间受力分析，并对不同荷载工况下不同曲线半径梁体的受力进行计算。通过分析不同影响因素下的箱梁内外腹板以及内外侧支座受力，得出了影响曲线梁桥空间受力的主要因素，对同类桥梁的设计有一定的指导意义。

Abstract:

The finite element model is established by using the general finite element software MIDAS/Civil to analyze the spatial force of the long-span curved girder bridge, and to calculate the force of the girder body under different load conditions with different curve radii. By analyzing the forces of the inner and outer webs and inner and outer supports of the box girder under various influencing factors, the main factors affecting the space force of the curved girder bridge are obtained, which has certain guiding significance for the design of similar bridges.
