预应力混凝土变宽箱梁的精细化分析

Refined anal Ysis of Prestressed concrete Widening Box Girder

预应力混凝土变宽箱梁受力复杂,有一定的空间效应;实现其精细化分析,对确保箱梁的结构安全意义重大。利用ANSYS软件对某桥梁变宽节点的预应力混凝土变宽箱梁进行实体建模分析,提高了分析精度,为变宽箱梁分析提供有效参考。

The prestressed concrete widening box girder is complicated in force and has a certain spatial effect.It is of great significance to ensure the fine structure of the box girder.The ANSYS software is used to simulate the solid prestressed concrete wide box girder of a bridge widening node,which improves the analysis accuracy and provides an effective reference for widening box girder analysis.
