Cable optimization of a long span cable stayed bridge in La Coruna (Spain)

This document describes an optimization problem of cable cross section of a cable stayed bridge considering constraints of cable stress and deck displacement. Since the bridge is still in study phase, the geometry and the mechanical characteristics are subjected to changes. In order to avoid creating different structural models, a program was produced to construct a model from geometrical and mechanical data and resolve optimization problem. At the end of the document, two examples are presented to show how this program works.
