Domain Transfer

This paper deals with the fitting of a rational function to an experimentally determined frequency domain transfer function. Examples show that the use of overdetermined fitted systems improve the identification in noisy situations. A method is presented, enabling the determination of the number of zero/poles of the system, and the relation to the rank of the matrix used in a least square identification method.

Negative Effect

The effect of non-zero initial conditions of measured structural responses on the structural parameter identification methods based on dynamic response sensitivity is investigated and an effective method is proposed to eliminate the negative effect. A twelve-story shear building structure is studied for validating the proposed method. Numerical simulation results show that the non-zero initial conditions of measured data bring larger identified errors in the dynamic response sensitivity methods. To overleap some measured data points in the initial period of the time interval is an effective method for eliminating the identified errors caused by non-zero initial conditions. The optimal number of overleaped data can be determined from the attenuation trend of the 1st-order free modal vibration of the structure.
