Wavelet-based Analysis for Pulse Period of Earthquake Ground-motions
Pulse period of earthquake records has been known as a key parameter in seismology and earthquake engineering. This paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. This type of motions often resulting from directivity effects is characterized by a strong pulse in the velocity time history of motion, in norm...
متن کاملNonstationary ARMA modeling of seismic motions
Discrete time-varying autoregressive moving average (ARMA) models are used to describe realistic earthquake ground motion time histories. Both amplitude and frequency nonstationarities are incorporated in the model. An iterative Kalman filtering scheme is introduced to identify the time-varying parameters of an ARMA model from an actual earthquake record. Several model verification tests are pe...

15 صفحه اولThe Duration and Amplitude Characteristics of Earthquake Ground Motions with Emphasis on Local Site Effects
Among various indices of earthquake ground motions, the maximum amplitude value and frequency content have been regarded as the most important indices for earthquake engineering. These indices are strongly affected by local site conditions. Also the fact that the duration of earthquake ground motion differs from site to site even during the same earthquake has been noticed by many researchers. ...
متن کاملCharacteristics of strong ground motions in the 2014 Ms 6.5 Ludian earthquake, Yunnan, China
The 2014 Ms 6.5 (Mw6.1) Ludian earthquake occurred in the eastern Sichuan-Yunnan border region of western China. This earthquake caused much more severe engineering damage than the usual earthquakes with the same magnitude in China. The National Strong Motion Network obtained large set of ground motion recordings during the earthquake. To investigate the engineering interested characteristics o...
