In the past centuries, masonry arches were the unique option for builders having to carry heavy loads over large spans. They were later neglected as the advantages of other solutions had been discovered. Today they represent a contemporary challenge for people engaged in heritage preservation. In accordance with international guidelines, the interventions that are avoidable should be avoided and an important responsibility is in the hands of civil engineers and architects. As the continuation of preliminary research published in the present journal, this paper proposes an innovative approach in the wellknown field of the Limit Analysis theory. After a short presentation of the context, the arch limit behavior is formulated as a constrained optimization problem solved through evolutionary strategies. A tool, implementing this approach in the Matlab environment, has been described and its validation has been proposed by a comparison with numerical results (ABAQUS) obtained on different morphologies.
