BUILDING EARTHQUAKE DAMAGE ESTIMATION DEVICE, METHOD OF USING BUILDING EARTHQUAKE DAMAGE ESTIMATION DEVICE, BUILDING EARTHQUAKE DAMAGE ESTIMATION METHOD AND PROGRAM

To estimate the degree of damage caused by an earthquake in a building without a seismograph.SOLUTION: A building earthquake damage estimation device acquires: a ground characteristic at a position of a building; ground characteristics of installation positions of a plurality of seismographs at positions different from the position of the building; and a structural characteristic of the building, being based on the ground characteristic of the position of the building and the ground characteristics of the installation positions of the plurality of seismographs, selects a seismograph for estimating the degree of damage, from among the plurality of seismographs, suitable for estimating the degree of damage caused by an earthquake in the building, acquires a time waveform of acceleration measured by the seismograph for estimating the degree of damage when an earthquake occurs, acquires a relation created in advance between the structural characteristic of a building, the time waveform of acceleration, and the degree of damage caused by the earthquake, and estimates a degree of damage of the building caused by the earthquake based on the structural characteristic of the building, the time waveform of acceleration, and the relation.SELECTED DRAWING: Figure 1 【課題】地震計が設置されていない建物の地震による被災度を推定する。【解決手段】建物地震被災度推定装置は、前記建物の位置の地盤特性と、前記建物の位置とは異なる位置である複数の地震計の設置位置の地盤特性とを取得し、前記建物の構造特性を取得し、前記建物の位置の地盤特性と前記複数の地震計の設置位置の地盤特性とに基づいて、前記複数の地震計から、前記建物の地震による被災度の推定に適した地震計である被災度推定用地震計を選択し、地震発生時に前記被災度推定用地震計によって計測された加速度の時間波形を取得し、予め作成られた建物の構造特性と加速度の時間波形と地震による被災度との関係を取得し、前記建物の構造特性と、加速度の時間波形と、前記関係とに基づいて、前記建物の地震による被災度を推定する。【選択図】図１
