Paper Abstract

For the identification of linear time-varying system, this study aims at a critical comparison and assessment of several recursive SISO (single-input single-output) parametric time-domain methods for the identification of seismic response of building structure. The methods are: • RLS method with constant trace, • RLS with variable forgetting, • Changing Spectrum Method, • RLS with selective forgetting, • wavelet analysis. For nonlinear system identification, this study aims at a critical assessment of the estimation of nonlinear restoring force. This study used the simulation seismic response data of a time-varying SDOF system and the full-scale pseudo-dynamic test data of a frame structure to discuss the characteristics of each method. Concise summaries of the methods, highlighting their principles and realizations, are provided.
