%0 Journal Article %T EVALUATION OF ENERGY AND SEISMIC EFFECT OF EARTHQUAKE WAVE BASED ON HHT ANALYSIS
基于Hilbert-Huang变换分析的地震动能量与震动效应评估 %A 刘强 %A 周瑞忠 %A 刘宇航 %J 力学与实践 %D 2008 %I %X The Hilbert spectra of frequency-time-amplitude can be obtained by HHT and be applied to dynamic analysis of the seismic signal. A quantitative index to evaluate strength of vibration effect by the use of the maximum energy (integral of the time-domain frequency density function) and the crest factor of earthquake wave are put forword, as a preliminary unified criterion of vibration effect, and the feasibility and reliability of the criterion are validated by several instances. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=5D344E2AD54D14F8&jid=0BF5C9FB031A532ED0A6D99DC4F6181A&aid=86B83B0732B95DCA9617235CDB5B402A&yid=67289AFF6305E306&vid=340AC2BF8E7AB4FD&iid=94C357A881DFC066&sid=2A8D03AD8076A2E3&eid=EA389574707BDED3&journal_id=1000-0879&journal_name=力学与实践&referenced_num=1&reference_num=12
