- Abstract
- An alternate procedure is presented for adjusting parameters, a procedure based on well known principles of optimization theory. In this procedure the parameters to be modified can be systematically adjusted using measured response data until, based on a predefined criterion, the best possible correlation is achieved between the predicted and measured response. The theoretical aspects of this procedure coupled with the selection of the mathematical model is known as system identification. This paper describes system idenification in the context of a set of experiments conducted on the shaking table at the Earthquake Engineering Research Center at the University of California at Berkeley. The primary objective of this testing program is to illustrate the viability system identification as a research tool in earthquake engineering.
