In 6th International Conference Integrity-Reliability-Failure. Lisbon, Portigal: INEGI/FEUP, 2018. ISBN 978-989-20-8313-1. Pp. 539-540978-989-20-8313-1http://hdl.handle.net/10400.21/8835This work intends to contribute to the development and use of time domain modal identification methods, namely the Maximum Likelihood Method (MLM) and the Covariance-Driven Stochastic Subspace Identification Method (SSI-Cov). Both methods are studied using numerically generated data and the SSI-Cov method is applied to the analysis of dam vibration records, due to environmental excitation.engTime domain modal identificationMaximum Likelihood MethodDam vibrationsconference object
