Sumario:The design, building and maintenance of  special  structures  such as bridges have generated  the need  to develop experimental  tests  in  order  to  identify,  in  a  precise manner,  their most  important  structural  properties  (statics and  dynamics). The  diffculty  to  use  forced  or  excitation-based  vibration  tests  in  a  controlled manner  brought about  the quest  for other useful and more applicable  identifcation methods such as  the use of excitation due  to ambient vibrations. The Ambient Vibration Testing (AVT) has yielded good results in bridges at both national and international levels. This is the reason for the interest in their study. This document presents a study of the principal aspects related to the application of AVT, focusing on different issues such as feld measurements, existing modal identifcation methods with ambient vibrations, and calibration of models in fnite elements from experimental data.
