consideration of the effects of near-field pulse-like GMs can considerably increase the risk of structural collapse in RC shear wall systems, based on the ratio of the pulse period of ground motion records to the elastic first mode period, in comparison to the near-field GMs without a pulse...

These studies showed that the resonant ground motion has its energy in a narrow frequency range and produces larger damage in the structure compared to ordinary records. Resonant or pulse-like ground motion has been observed in near-field records with directivity focusing or fling effects. Such ...
abundant low frequencies is found in the responsive spectra for near-field pulse-like ground motions.It is recommended that the peak ground velocity(PGV) and ground energy density(E() are the parameters that can be used to estimate the damage degree of structures in the near-field environment....

To this end, the ground motion intensity measures are firstly compared with existing models; it is shown that PGA and spectral accelerations from both the non-pulse-like and the pulse-like motions are overall captured by the Zhao et al. (Bull Seismol Soc Am 96(3):898–913, 2006, https:...
