Abstract
The first part of the present study deals with application of the theorems by Castigliano to the Finite Element Method (FEM) to find out the form that includes only compressive stresses but no tensile stresses of masonry arch bridges subjected to dead load. A numerical analysis on Mosca's bridge over the Dora Riparia, Turin, corresponds well to the result by Castigliano. The arch is maintained by compressive forces transmitted everywhere within a mass of masonry. The second part discusses the effect of wedging for repair and maintenance of masonry arch bridges by means of FEM. Numerical simulation shows practical efficiency to strengthen cracks by wedges.
