Research on Rigidity Distribution between Arch and Girder for Tied Arch Bridges with Trough Girder

摘要

In order to explicitly specify the force characteristics of tied arch bridge with trough girder, this paper focus on the tied arch bridge vertical stiffness analysis under different rigidity distribution between arch and girder. The paper based on a tied arch bridge with trough girder which the span is 96 meters, changing the rigidity distribution between arch and girder by different arch rib section. Contrasting the force characteristics on the premise of conforms to the national standards, and then gets the most suitable rigidity distribution between arch and girder.
