Long-period ground motions from the 2003 Tokachi-oki earthquake
Journal of Seismology, 2007We study characteristics of long-period ground motions from the 2003 Tokachi-oki earthquake (Mj 8.0), a large interplate earthquake, based on spatial distribution maps and attenuation relationships for four kinds of peak ground velocity (PGV) value. The first kind (PGV(WB)) is obtained from a maximal value of vector sum of the three-component, wide ...

Pseudo relative velocity spectra of earthquake ground motion at long periods
Soil Dynamics and Earthquake Engineering, 1995Abstract This paper analyses the processes which govern structural response, and uses observations of strong earthquake ground motion to propose quantitative extrapolation of pseudo relative velocity spectral amplitudes to long (100 > T > 1 s) periods.

ACCELERATION RESPONSE AMPLIFICATION RATIO CONSIDERING LONG-PERIOD GROUND MOTIONS
In the seismic design standard (ASCE7), the acceleration response amplification ratio of non-structural components is 1–7.5, depending on the height to which the non-structural components are attached. The acceleration response amplification ratio of the non-structural components has been proposed for short-period ground motions.Kim, J.C., Oh, S.H.
