PRELIMINARY OPTIMAL DESIGN OF CABLE-STAYED BRIDGES

A methodology for preliminary design of cable-stayed bridges using optimization techniques is presented. A simple model of the bridge, comprising beam elements for the longitudinal deck girder and tower and truss elements for stay cables, is used. The computer program saddle is used for optimization. Constraints are placed on stresses, displacements and member sizes under multiple loading conditions. The methodology enables the designer to vary the arrangement and size of stay cables and cross-sectional dimensions of the longitudinal deck girder. Consequently an aesthetically pleasing as well as an economical and feasible design of a cable-stayed bridge can be obtained quickly and efficiently. (Author/TRRL)
