摘要

摘要: 对基于环境激励下运用时间序列法ARMA模型对工程结构模态参数的识别进行研究。结合传统模态试验,对一个多层框架结构进行了模态参数识别的对比试验,试验结果显示:二者在模态参数识别上具有高度的一致性。分析表明:时间序列法ARMA模型能够在传统模态试验难以进行的环境下,准确有效地识别工程结构的模态参数,为结构的在线监测和抗震设计等提供模态参数,具有一定的工程应用价值。

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.
