Abstract: Despite the significant advance of new technologies applied in civil engineering, the structures continue subjected to the occurrence of faults which are produced in normal conditions of use. The detection of these faults may be done by the analysis of some dynamic characteristics as frequencies and mode shapes. This fact implies that such characteristics must be identified accurately in order to produce reliable results about structural health. Artificial neural network may be also used as an important tool in the evaluation of structural integrity. This work presents an experimental analysis, in which a laboratory beam was submitted to different vibration tests. In the attempt to establish a suitable methodology for structural evaluation, the method of artificial neural network was applied in order to identify the damage location and the obtained results were very satisfactory.
