Abstract: Earthquake-induced pulse-like ground motions are often observed in near-source conditions due to forward-directivity. Recent worldwide earthquakes have emphasised the severe damage potential of such pulse-like ground motions. This paper introduces a framework to quantify the… read more here.

DOI: 10.1007/s42107-021-00385-w
Abstract: The near field pulse-like ground motion has significant effects on a long-period structure like a wind turbine. Such pulses can be due to source effect (directivity) or site effect (presence of basins), to name a… read more here.

DOI: 10.1016/j.soildyn.2020.106347
Abstract: Abstract Long-period pulse-like ground motions in the near-field are likely to induce severe damage to large structures due to resonance at the natural frequencies of engineered construction. To investigate the origin and characteristics of large… read more here.

DOI: 10.1016/j.soildyn.2021.107009
Abstract: Abstract Near-fault ground motions have distinctive features different from typical far-field ground motions. The approach detects near-fault pulse-like ground motion based on the variational mode decomposition (VMD) technique. First, the original ground motion can be… read more here.

DOI: 10.1155/2019/3858457
Abstract: Isolated bridges are commonly designed in the near-fault region to balance excessive displacement and seismic force. Optimal intensity measures (IMs) of probabilistic seismic demand models for isolated bridges subjected to pulse-like ground motions are identified… read more here.

DOI: 10.1785/0120200141
Abstract: Pulse-like ground motions cause severe damage in structures at certain periods. Hence, pulse effects need to be considered during probabilistic seismic hazard analysis and seismic design in the near-fault region. Traditional ground-motion models used to… read more here.
