Methods of identification for structural dynamic systems are reviewed in this report. Emphasis is placed on methods relevant to the identification of linear and nonlinear behavior of structures subjected to such environmental loads as ground motion due to earthquakes, wind-generated pressure and wind-induced ocean wave forces. The methods considered are the least square, instrumental variable, maximum likelihood and a method utilizing the extended Kalman filter. In order to verify the validity of these methods, numerical simulation studies are carried out utilizing mathematical models of a suspension bridge, offshore tower and building structure. On the basis of such simulation studies, the efficiency of these methods are investigated under several conditions of observational noise. © 1989.
