summary Optimal design of continuous prestressed systems is stated in a nonlinear programming form. The design variables are the concrete dimensions, tendon coordinates, and prestressing force. The constraints are related to various behavior and design requirements and the objective function represents the overall cost. Some simplified models, intended to improve the solution efficiency, are presented. These include: explicit formulations of the general problem and the problem of minimizing the concrete dimensions; linear programming formulation of the tendon configuration and prestressing force optimization; and direct determination of the prestressing force for given concrete dimensions and tendon coordinates. Some examples illustrate the various problem formulations and solution methodology
