斜拉桥钢—混结合段应力特征分析

Study on the Stress Characteristics of Steel—Mixing Section of Cable-Stayed Bridge

以某斜拉桥钢-混结合段为研究对象,利用ABAQUS通用有限元软件建立钢-混凝土结合段三维有限元模型,根据计算得到的结合段位置处最不利工况内力,对钢-混凝土结合段进行局部应力及结合段受力规律进行分析,为进一步改善设计提出依据。

Taking a cable-stayed bridge steel combined section as the research object, using the general finite element software of ABAQUS steel and concrete combination section of 3 D finite element model is established, according to the combination of the calculated period of location the most unfavorable condition of internal forces, local stress analysis was carried out on the steel and concrete combination period, at the same time, the regularity of combination section is analyzed, in order to further improve the design basis.
