Abstract

木造建物の全壊といった建物の大きな被害と対応した震度を迅速に計算するために,計測震度の算定に用いるフィルタの周波数特性を修正することを試みた.具体的には,過去に発生した地震動の観測点周辺の木造建物全壊率と対応するようにフィルタの周波数特性を修正した.その結果,フィルタの周波数特性を修正することにより,木造建物の全壊率と対応した震度を迅速に計算できることがわかった.

In order to calculate seismic intensity corresponding actual heavy damage to houses and buildings promptly, we tried to modify the filter used in the calculation of JMA seismic intensity. We modified the filter so that the calculated JMA seismic intensity corresponds to the actual heavy damage ratios of houses and buildings around the strong ground motion observation sites in the past earthquakes. We found that we could calculate the seismic intensity promptly by modifying the filter used in the calculation of JMA seismic intensity.
