چکیده    Pulse period of earthquake records has been known as a key parameter in seismologyand earthquake engineering. this paper presents a detailed characterization of this parameter for a special class of earthquake records called pulse-like ground motions. thistype of motion is often resulted from directivity effects and is characterized by a strong pulse in the velocity time history of motion, in normal-fault component. wavelet analysis was used as a powerful and useful technique in the analysis of non-stationary signals in this study. the period of velocity pulses is basically determined using the pseudo-period of the mother wavelets. the effects of three different mother wavelets on results were investigated and new empirical predictive equations for pulse period have been derived. © 2013 elsevier b.v.
