In the mid Eighties, researchers at the Department of Building Technology and Structural Engineering at Aalborg University, Denmark, started using time domain models for system identification of civil engineering structures. in the past decade the results of this work are reported in several papers and in three Ph.D. theses. a standard feature of the work has been the use of the so-called auto-regressive moving average (ARMA) models for time series modelling. the rationale is that the ability of these models to supply an accurate estimate of the modal parameters of a structural system on the basis of discretely sampled response.
