Abstract

Blast vibration monitored in terms of peak particle velocity (PPV) could not explain completely its effect on structures. Surface buildings at a distance of one km were damaged though the PPV did not exceed 7 mm/s. Spectral analysis of the vibration records indicated low frequency ground vibrations which were possibly responsible for the damage. Further investigations were carried out by recording structural response to ground vibration on single storied structures. The natural frequencies of the structures were 8-18 Hz. It was observed that the ground vibrations were amplification was a function of the frequency of the ground vibration. Authors suggest that blast vibration must be analysed for PPV as well as frequency in order to assess its damage potential to surface structures.
