Abstract

Abstract

Engineering structure parameter identification method applied with time series ARMA modeling under ambient ex citation was researched. Then combined with traditional model experiment theory two check model experiments were done on a multistorey frame, and the results of the two experiments were highly consistent. The analysis indicated time series ARMA model can ex actly and validly identify model parameters of engineering structure under circumstances which traditional model experiment may be difficult to process, and with these merits it had value in engineering application for providing model parameters for on-line monitor and active control of engineering structure.
