Abstract
This paper presents an algorithm for a time series analysis-the high-o rder multivariate autoregressive model M-AR(P). The theory of the mode l and the application in modal parameter identification of structures excited by natural random forces is described. A water transmission to wer is taken as a real example to illustrate the application procedure of this algorithm. Good results in natural frequencies, damping ratio s, mode shapes, as well as power spectra and coherence functions ident ified by this model prove the advantages and usefulness of the algorit hm.
