This paper presents an application of a powerful thin-walled element a
nd a special cable element for three-dimensional modelling of steel ca
ble-stayed bridges. Both linear and nonlinear effects are considered,
as geometric nonlinearity may arise from the finite displacement of th
e bridge deck as well as the cables. As cable-stayed bridge decks are
normally built-up thin-walled cross-sections, the effects of flexural-
torsion coupling as well as warping restraint are included. Finally, s
everal examples of cable-stayed bridges serve to demonstrate the effec
tiveness of this most comprehensive model.
