A WAVELET-BASED PROCEDURE FOR MINING OF PULSE-LIKE GROUND MOTIONS FEATURES ON RESPONSE SPECTRA
The main objective of this paper is to present a wavelet-based procedure to characterize principle features of a special class of motions called pulse-like ground motions. Initially, continues wavelet transform (CWT) which has been known as a powerful technique both in earthquake engineering and seismology field is applied easily in automated detecting of strong pulse of earthquakes. In this pr...
متن کاملGENERATION OF OPTIMIZED SPECTRUM COMPATIBLE NEAR-FIELD PULSE-LIKE GROUND MOTIONS USING ARTIFICIAL INTELLIGENCE
The existence of recorded accelerograms to perform dynamic inelastic time history analysis is of the utmost importance especially in near-fault regions where directivity pulses impose extreme demands on structures and cause widespread damages. But due to the scarcity of recorded acceleration time histories, it is common to generate proper artificial ground motions. In this paper an alternative ...
متن کاملWavelet-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 کاملSeismic Fragility Assessment of Steel SMRF Structures under Various Types of Near Fault Forward Directivity Ground Motions
In this paper, the seismic collapse probability of special steel moment-resisting frame (SSMRF) structures under near fault pulse-like and far fault ordinary ground motions is evaluated through fragility analysis. For this purpose, five sample frames with 3 to 15 stories are designed and imposed to the ground motion excitations with different characteristics. Fragility curves are derived for th...
متن کاملVector-valued intensity measures for pulse-like near-fault ground motions
A vector-valued intensity measure (IM) is shown to account for the effects of pulse-like near-fault ground motions. This class of ground motions, which are indicated by the presence of a velocity pulse, can cause large responses in structures and their effects are not well described by traditional intensity measures such as spectral acceleration at the structure’s first-mode period, Sa(T1). It ...
