Abstract

Stone arch bridges are part of the cultural heritage for many countries. Their construction was based on materials easily available locally, e.g. stones and mortar. The weak-in-tension material dictated the shape of the structures. Many stone arches still survive and some are even used as pedestrian bridges or bridges for light traffic, therefore a more detailed analysis of these monuments is of great interest. For this purpose, many models have been developed for the study of their mechanical behaviour. Because of the great development of computers the proposed methods have become quite sophisticated and include large computational models. In this framework nonlinear finite element analysis is used extensively for the study of stone arches. While many researchers have examined the nonlinear behaviour of these structures or their collapse, relatively few have studied their reinforcement and restoration. In the present chapter both the nonlinear and limit analysis as well as a method of reinforcement with fibre reinforced polymers (FRP) materials are studied. Discrete finite element models of nonlinear mechanics have been established for this purpose. The unreinforced model is presented initially and compared with methods of limit analysis. Then a method of reinforcement by applying FRP materials in the arch is proposed and numerical examples are given.
