Dynamic measurements on bridges: design, rehabilitation and monitoring

This paper aims to stress the relevant role that the experimental assessment of the dynamics of bridges can play during the phases of conception and design, construction, reception, rehabilitation and monitoring (temporary and long-term). The importance of the experimental approach in these phases is essentially derived from experience gained from involvement in dynamic tests on several bridges: the Jindo (South Korea), Infante D. Henrique, Vasco da Gama, Luiz I (Portugal) and Z-24 (Switzerland) bridges.
