Feasibility of dynamic test methods in classification of damaged bridges
conference paper
Bridges may need to be assessed and restored in military operations. The ability to make an assessment quickly without the use of a baseline data set is essential if a correct decision about the safety of the bridge is to be taken. To acquire knowledge of the possibilities and limitations of detecting damage through dynamic measurements, a series of experiments was carried out consisting in static and dynamic tests of concrete slabs with different degrees of damage. By carrying these tests it was possible to gain insight as to how the dynamic response changes at different damage levels. In the present article, the information which can be obtained from modal parameters relating to the presence and extent of damage and possibly the strength of the structure is discussed.
