Abstract

Abstract

In recent years, beam-arch combination system bridges in China has been developing rapidly, the V-shaped continuous rigid frame system beam-arch combination bridge is a new type of structural system. The Fuzhou WanBian Bridge was taken as the engineering background, using the large-scale universal finite element software to establish a bridge structure model, mechanical analysis of key joints in the construction stage of the V-shaped continuous rigid frame system beam-arch composite bridge was carried out, including stress analysis of the V-braced position in the cantilever state of the box girder, internal force analysis of arch ribs during the stage of pouring concrete into the arch rib tube, stability analysis of steel pipe arch ribs, and dynamic characteristic analysis. Finally, the study of key joints during the construction stage of the bridge revealed that the calculated stress of the bridge during the construction stage met the requirements of the specifications, various materials would not exhibit stress yielding phenomenon during the pouring process.
