• Resumen

  • A methodology to obtain the minimum weight of cables in cable-stayed bridges has been developed. The number of cables, anchor positions on the deck, the crosssectional areas and post-tensioning cable forces have been considered as design variables simultaneously in the optimization process. Two different strategies are proposed using both genetic and gradient-based optimization algorithms. Finally, the Rande Bridge (Vigo, Spain) has been chosen as the application example of both approaches.
