Abstract

In this paper a method for automatic design of the prestress in continuous bridge decks is presented. In a first step of the procedure the optimal prestressed force for a completely geometrically defined and feasible prestress layout is obtained by means of linear programming techniques. Further on, in a second step the prestress geometry and minimum force are automatically found by step descent optimization techniques. Finally this methodology is applied to two span continuous bridge decks and from the obtained results some preliminary design rules can be drawn.
