Abstract
To research structural performance of extra-large-span cable-stayed bridge under different sec- tion forms, with the engineering background of a 800m main-span cable-stayed bridge with steel truss girder, the cable-stayed bridge with steel box girder is designed according to the current bridge regulations when two bridg- es are designed in an ultimate state of the carrying capacity, so the maximum stress and minimum stress of the stress envelope diagram are substantially the same. A comprehensive comparison is given to two types of bridge on the aspect of static force, natural vibration frequency, stability, economic performance and so on. Analysis results provide future reference for the large-span cable-stayed bridge to select between the steel truss girder and the steel box girder.
Highlights
Cable-stayed bridge is one of China’s most popular bridge types among large-span bridges
With the construction of Yachi River Bridge, Hutong Yangtze River Bridge, Tianxingzhou Yangtze River Bridge and other large-span cable-stayed bridge with steel truss girder, the large-span cable-stayed bridges are gradually applied to rail transport and some places with poor transport conditions
Analysis shows that the buckling of the steel box girder on the previous five orders is buckling in plane, which is mainly an overall buckling of girder
Summary
Cable-stayed bridge is one of China’s most popular bridge types among large-span bridges. Among the large-span cable-stayed bridges that have been built up, the steel box girder is widely used. The following reasons are analyzed by the author: simple structural design, convenient construction, welding and bolting, safe and reliable structure; the steel box girder commonly adopts factory prefabrication and spot lifting construction, which can effectively shorten the construction period with attractive appearance. With the construction of Yachi River Bridge, Hutong Yangtze River Bridge, Tianxingzhou Yangtze River Bridge and other large-span cable-stayed bridge with steel truss girder, the large-span cable-stayed bridges are gradually applied to rail transport and some places with poor transport conditions
