Abstract(s)
This 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.
