• EMPIRICAL PREDICTIVE MODEL FOR LONG-PERIOD (1-15 SEC) GROUND MOTION ON HARD ROCKS

抄録

To assess the long-period (1-15 sec) ground motion has become a critical issue associated with a recent rapid increase of tall buildings, base-isolated structures, long-span bridges, large storage oil-tanks and so on. We obtained empirical models of 5% and 1% damped acceleration response spectrum for long-period ground motion on hard rocks. We only used the down-hole data of the KiK-net at 161 selected hard rock sites where the S-wave velocity exceeds 2.0km/s at depth of down-hole. We used the 2,078 records from larger magnitude than 5.7 and events shallower than 60km. Considering the quality of data, the records of shorter distance than 500km were used. In addition, we verified validity of our empirical predictive model by comparing with the observed individual strong ground motion records.
