- The developments and progresses of the engineering modelling of earthquake ground motion are reviewed in the paper, this part discusses the commonly used seismological models. 分析了地震动模型化研究的发展概况与特点,对地震动模型化研究中常用的地震学模型进行了综述与评价。
- The Hilbert spectra resulted from HHT can provide more significant description of time-varying frequency composition and thus represent the non-stationarity of earthquake ground motion more accurately. 由HHT方法得到的Hilbert功率谱能清晰地显示随时间变化的频率特征,因而能更精确的表达地震动时程频域内非平稳的特性。
- The earthquake ground motion is characterized by its three tightly correlated attributes: amplitude, frequency content, and duration.Its panorama can hardly be viewed from a single perspective. 地震动特性有三个要素:振幅、频谱和持时,三者之间相互作用,孤立研究任何一个方面都难以全面地反映地震动作用的全貌。
