Multicriteria Optimium Design of Prestressed Concrete Bridge Girbers

摘要

This paper describes an application of an optimization strategy to the design of prestressed concrete box girders. The problem is posed as a multicriteria optimization with goals of minimum cost, stress and displacements. The optimized solution complies with the ultimate and serviceability limit states defined in the new European Codes of Practice (Eurocodes): The validity of the proposed techniques is examined by means of numerical examples.
