Structural Identification Parametric Models and Idefem Code

This chapter describes structural identification techniques based on parametric models. Focus is given to physical models, where the inertial and mechanical characteristics are the goals of identification. These models are more attractive than modal models as they potentially yield local information. To reduce the computational effort of this complex problem, a refined algorithm is implemented which identifies the parameters of a structure’s finite element model. Experimental data, usually represented by selected modal quantities, are used in the identification process.
