| Abstract: | This paper analyzes the influences of various factors on the lateral stability of long span half through arch bridge using the common finite element method software ANSYS, based on a 198 meter CFST skeleton arch bridge in Chun'an of Zhejiang Province. These factors include the rigidity of arch, the rigidity, location and form of lateral connections. Conclusions from this paper should provide valuable references to the design and construction of similar projects. |
