Abstract

Measurements of flexural vibration of a beam and the same beam carrying a known concentrated mass are used to identify the structural parameters of the beam, such as mass and stiffness. From the eigenfrequencies of these two structures and analytical solutions of the dynamic response, the structural parameters can be determined with satisfactory accuracy. The method is non- destructive and can be applied to structures for which an analytical description is available. The main features of the method are as follows: (a) it requires measurements of the structural response at a single point only, measurements performed at several points offer correlated and more reliable results; (b) it is applicable to many one-dimensi
