| Abstract: | The paper presents the analytical relationship for the changes of the natural frequencies at the occurrence of a transversal damage on a continuous beam with three spans using the Euler-Bernoulli theory, regardless of the location of the damage on the structure. When the damage appears on the beam, the changes of the natural frequencies can be highlighted by the square of the mode shape curvature for any location of the damage on the structure. The paper exemplifies the changes in natural frequencies for two possible locations of the damage. |
