LONG-PERIOD GROUND MOTIONS FROM RECORDED ACCELEROGRAMS LOMA PRIETA EARTHQUAKE OCTOBER 1989 M7.1

抄録（英）：
The long-period content of the strong-motion accelerograms from the Loma Prieta earthquake is analyzed for a clear picture of the overall ground motions. Shear waves having periods in the 3.5 to 4 s, and 5 to 7 s ranges travel across four groups of stations. Displacement accuracies are of the order of 0.5 cm for most of this data. Resonances associated with shear waves of 1.5 s period are responsible for about 3/4 of the differential displacement necessary for the failed 15 m section of the Bay Bridge to shift off its seating.
