Correct design of cable-stayed bridges is a key issue in bridge engineering in order to reach structural efficiency, maintaining adequate structural performance during time, respecting safe life. A good performance design of cables in strand bridges could be reached locally by adopting specific structural details in order to minimize fatigue stresses, and globally by geometrical optimization of cables. This paper introduce the general problem of optimal arrangement for cable- stayed bridge taking into account fatigue phenomena. Parametric analyses related to various geometric configurations of the cables are developed and some new insights for arranging geometric configuration of cable-stayed bridges are shown. |
