Comparación entre la estimación de parámetros modales de estructuras a partir de análisis modal clásico y operacional con modificaciones de masa

It will thus be possible to reliably determine the modal parameters of the structure and their alteration due to mass modification. For this purpose, the proposed methodology is applied to a large span metal bridge, unique for its slenderness, with a span/depth ratio of 56.6, the lowest recorded on a bridge, as figured in the Guinness Book of Records since 2007.
