摘要：

In this work, a vibration based damage identification technique (VBDIT) is used to determine the presence of damages in metallic structures, using the undamaged structure information as reference. A complex structure is used in order to contrast the results obtained with those reported for techniques previously employed specially on single beam simulated structures. A finite element model of the structure is developed and validated as a support tool for the study. Theoretical and experimental modal analysis techniques were used as the main tool for damage identification.
