Recorded ground motions affected by forward directivity effects indicate that velocity pulse may arrive at a relatively later stage of the record even though it is believed to arrive at the beginning of velocity time-history. An attempt has been made to correlate arrival instant of velocity pulse with a few seismological and pulse parameters. To assess the effect of velocity pulse arrival on seismic response of structures, a series of oscillator with different hysteretic behaviour is considered. The results of nonlinear time-history analyses indicate that the late arriving pulse motions...
