OVERVIEW

Cable-stayed bridges are often considered as landmarks due to their modern and magnificent appearance.  As a bridge design engineer, it is a great honour to design this type of beautiful bridge. However, the static analysis of cable-stayed bridge is quite different from other bridges.

 

This session will mainly show some fundamental knowledge and skills of modelling cable-stayed bridge.

KEY POINTS

Key Point 1:Overview of cable-stayed bridges

Cable-stayed bridges are highly statically indeterminate due to the redundant DOFs provided by the cables. Cable-stayed bridges are also active bridges because engineers can change the structural state by adjusting cable forces.

 

Key Point 2:How to model the components of a cable-stayed bridges

Pile-soil interaction can be modelled based on Winkler theory and m method. Rigid links can be used to model the connection between components. Girders can be modelled using the fish-bone model. The sag effect of cables can be taken into account by cable elements.

 

Key Point 3: Optimisation of cable forces

A well defined level of cable forces will allow optimised performance of bearings, girders, pylons and cables.  The Stiff Cable method can be used to find approximate cable forces. The Unit Load method can be used to optimise cable forces and in addition develop an understanding of the structural effects of cable forces.
