Description
Summary:The instrumental rapid monitoring of the dynamic (ambient) response of a balanced cantilevered ravine bridge of Egnatia Motorway during its construction phases, when subjected to wind and other construction loads, was implemented. The aim is to verify the conformity both of the sequential construction phases and of the final completed structure of the ravine bridge of Metsovo to the design predictions. In this paper the modal frequencies, damping ratios and modeshape components of the completed balanced cantilever of pier M3 were identified from ambient acceleration records, and its analytical dynamic model was updated to determine the actual stiffness and mass properties of the structure.
