Abstract

A system realization algorithm is used to identify a structural model directly from input and response measurement data. The algorithm starts with computing the information matrix to derive a special correlation matrix that in turn produces the system observability matrix. A system model can then be identified from the observability matrix. Finally an algorithm was developed which produced a modal model, including stiffness matrix and damping matrix, from this state space system realization. Verification of the method through both numerical simulation and experimental data from shaking table test is carried out in this study.
