In this paper, a new methodology is proposed to identify modal and physical parameters of linear non-viscously damped multi-degree-of-freedom systems using recorded time-histories of their dynamic response. The methodology is based on the identification of a symmetric state-space realization of the system, whose modal parameters (spectral and modal matrices) are subsequently used to determine the physical parameters (mass, stiffness and damping matrices) of the model in second-order form.

Abstract

In this paper, a new methodology is proposed to identify modal and physical parameters of linear non-viscously damped multi-degree-of-freedom systems using recorded time-histories of their dynamic response. The methodology is based on the identification of a symmetric state-space realization of the system, whose modal parameters (spectral and modal matrices) are subsequently used to determine the physical parameters (mass, stiffness and damping matrices) of the model in second-order form.
