Paper Abstract

To identify dynamic parameters of structural systems, we have to solve non-linear optimization problems because the system transfer equation of a structural system is usually a non-linear function of the system's parameters. The purpose of this paper is to develop a method to linearize an observation equation with respect to structural parameters, which is derived from the system transferequation, and used it to identify the dynamic parameters of linear and non- linear dynamic structural systems. The numerical examples were satisfactory for identifying the dynamic parameters of model structures with eight degrees of freedom.
