Analysis of Multi-Pylon Cable-Stayed Bridges with Intersecting Cables

Abstract:

For the intermediate pylons of multi-pylon cable-stayed bridges can’t be connected by backstays to fixed points, it is possible to produce greater horizontal displacements in the top of towers under the action of external loads. Therefore, it is an important problem to obtain adequate structural stiffness in the design of multi-pylon cable-stayed bridges. In this paper, methods of improving stiffness of multi-pylon cable-stayed bridges are discussed. Multi-pylon cable-stayed bridges with intersecting cable are studied. Some useful recommendations were given for the design of multi-pylon cable- stayed bridges by numerical calculation.
