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

Abstract

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 the design phase, the geometry and the mechanical characteristics are subjected to changes. In order to avoid creating different structural models, a computer code was written to produce a model from geometrical and mechanical data and solve the optimization problem. At the end of the document, two examples are included to show the capabilities of the methodology presented.
