DAMPING IDENTIFICATION FOR BUILDING STRUCTURES SUBJECTED TO EARTHQUAKES: A REVIEW
This paper reviews existing methods employed for the identification of damping in building structures and the properties, practical application and problems commonly associated with the most important of those methods. Some characteristic examples are presented to demonstrate the capabilities of these methods. Emphasis is given to the application of these methods to identify damping when a seismically excited building structure vibrates in the non-linear region. Further needs on damping identification are also addressed.
