The results of a series of dynamical tests on a damaged reinforced concrete bridge are presented in this paper. Several damaged configurations were studied and the corresponding variation of modal parameters was observed. Both harmonically forced and ambient dynamical tests have been conducted comparing the ability of different techniques to capture the structural modifications induced by damage on the lower natural frequencies and modal shapes of the bridge.

Abstract
The results of a series of dynamical tests on a damaged reinforced concrete bridge are presented in this paper. Several damaged configurations were studied and the corresponding variation of modal parameters was observed. Both harmonically forced and ambient dynamical tests have been conducted comparing the ability of different techniques to capture the structural modifications induced by damage on the lower natural frequencies and modal shapes of the bridge.File in questo prodotto:
