Abstract

Structural elements in cable-stayed bridge decks can undergo large deflections under load or may be required to control the internal forces of a specific cable. The displacement must be restored and/or the cable force must be controlled and limited according to the desired target. The control of nodal displacements and internal bar forces of cable-stayed bridge structures is presented theoretically and experimentally in this paper through the use of a relatively simple and direct method, which involves calculating the required length actuations within a single formulation. The technique of multi-iteration adjustment is also presented, which is an effective way of eliminating or minimising errors that can occur in the practical adjustment process.
