| Abstract: | Using the finite element software TDV RMV8i, this paper carried on the modeling of a prestressed concrete open-spandrel rigid-frame arch bridge. According to the actual situation of the bridge construction and use, it also carried out the buckling stability analysis and drew the important conclusions, which provided the reference for the same type of bridges in the design and construction. |
