This work deals with the identification of modal frequencies for an existing footbridge through an output only technique. The structure has a continuous curved girder and belongs to a frequently used structural system all around the world in urbanized areas. Consequently, the development of a suitable and effective monitoring is of paramount importance for guaranteeing continuous serviceability and safety. Long-gauge fiber optic strain sensors are installed along entire structure, including locations where local damages, or deteriorations, are expected. Besides, a wireless network monitoring system is under development to be applied in parallel to fiber optic one for a comprehensive assessment of the stiffer component (the main-span) of the bridge where only minor strains are registered by the fiber optic sensors.

Abstract: | This work deals with the identification of modal frequencies for an existing footbridge through a...n output only technique. The structure has a continuous curved girder and belongs to a frequently used structural system all around the world in urbanized areas. Consequently, the development of a suitable and effective monitoring is of paramount importance for guaranteeing continuous serviceability and safety. Long-gauge fiber optic strain sensors are installed along entire structure, including locations where local damages, or deteriorations, are expected. Besides, a wireless network monitoring system is under development to be applied in parallel to fiber optic one for a comprehensive assessment of the stiffer component (the main-span) of the bridge where only minor strains are registered by the fiber optic sensors. | |
