✦ Synopsis
In the present paper, the authors propose a new experimental method of identifying the set of spatial matrices. This method identifies the spatial matrices, namely mass matrix, damping matrix and stiffness matrix, which describe the properties of dynamic structures, using experimentally measured FRFs (Frequency Response Functions) within the frequency range of interest. In this paper, the theory developed for this method is introduced. The validity of the proposed method is verified by its application to an actual frame structure using experimental FRFs measured by hammering tests.
