Effects of response spectrum of pulse-like ground motion on stochastic seismic response of tunnel [PDF]
, 2023 It is widely accepted that near-fault pulse-like ground motions potentially cause more severe damage to structures than ordinary ground motions. However, the effects of stochastic pulse-like ground motions on underground structures are not effectively ...

DESIGN RESPONSE SPECTRA FOR PULSE-LIKE GROUND MOTIONS
Journal of Structural and Construction Engineering (Transactions of AIJ), 2010 In recent inland shallow earthquakes, pulse-like ground motions have been observed which subsequently caused severe damage to buildings. However, the response of buildings to pulse-like ground motions has not been sufficiently characterized yet. In this study, we investigate the effect of pulse-like ground motions on the design of structures and define
