Structural Modal Parameter Identification Based on ARMA Model

Abstract:

Structural parameter identification is a significant technology to show certain characteristics and material damage of earthquake resistant structures or building materials in structural engineering and seismic engineering field. ARMA time-series method is belonged to time-domain method. ARMA time-series method for estimating the modal parameters of structure is presented in this paper. In order to verify the accuracy of the method, analytical simulation studies are performed for a frame structure model on the basis of simulated data under white-noise excitation conditions. And the results are analyzed and discussed. The research demonstrates that ARMA time-series method can effectively identify the modal parameters.
