#Motion pulse zip file#
zip file contains plots of pseudo-velocity spectra for the 91 pulse-like ground motions identified in the companion paper, along with spectra from their extracted pulses and residual ground motions. Plots of pseudo-velocity spectra from pulse-like ground motions. This Excel spreadsheet provides the data from Figure 1 of the manuscript in electronic form, and adds a few additional fields to the table. Summary results for pulse-like ground motions. The results are provided in the same format as the NGA flatfile ( ), so they can be easily appended into that larger flatfile for use in ground motion studies. Using these basic results, a user can easily determine how the set of identified pulse-like ground motions changes as the classification procedure is modified.

The script "main_analyze_ground_motion.m" calls the other functions provided in the. zip file contains the basic functions used in the ground motion classification procedure. The first line of each file contains the time step and number of points in the ground motion, and the remaining rows contain the accelerations over time in units of g. Record numbers correspond to those used in the paper and elsewhere on this website. The original record, extracted pulse, and residual record are labeled accordingly. These text files contain acceleration time histories for the 91 fault-normal pulse-like ground motions. Plots of the original velocity time history and extracted pulse are given, along with metadata from the NGA "flatfile" that may be useful for determining whether the observed pulse was caused by directivity effects.Īcceleration time histories of pulse-like ground motions and extracted pulses.
