Full-Azimuth Quantitative Identification of Near-Fault Pulse-Like Ground Motions Based on M&P Wavelet
Quantitative characterization and proper parameterization of pulse-like ground motions have been a challenge for earthquake engineering research. The azimuth of the pulse-like ground motion has a great influence on the structural damage. This study proposes a full-azimuth quantitative identification method to determine the pulse inherent in near-fault pulse-like ground motions. A support vector machine was used to classify the records into pulses or non-pulses based on a new pulse index. Records with a pulse index greater than zero can be classified as pulse-like. The proposed approach was used to identify pulse-like features in arbitrary orientations and can determine the strongest pulse azimuth.
