    FOUNDATION PART DAMAGE ESTIMATION DEVICE AND FOUNDATION PART DAMAGE ESTIMATION PROGRAM

    New search for: TOJO TOSHIKI

    To provide a foundation part damage estimation device and a foundation part damage estimation program that can estimate whether there are earth-quake caused damages in the foundation part using foundation part sensors installed in the upper part of the foundation part.SOLUTION: A foundation part damage estimation device 100 includes a building vibration estimation part 102B which estimates the building vibration mode in normal times and the building vibration mode immediately after an earthquake by using a building sensor 18 provided on each floor of the building, a foundation vibration estimation part 102C that estimates the foundation vibration mode in normal times and the foundation vibration mode immediately after an earthquake by using a foundation sensor 20 provided in the upper part of the foundation of the building, and a damage estimation part 102D which estimates that the foundation of the building has been damaged by earthquake when the normal building vibration mode is used to standardize the ground vibration mode immediately after an earthquake and the difference between the mode vectors of the standardized ground vibration mode immediately after an earthquake and the normal ground vibration mode is greater than or equal to a predetermined difference.SELECTED DRAWING: Figure 3

    【課題】地震による基礎部の損傷の有無を基礎部の上部に設置された基礎部センサを用いて推定することができる基礎部損傷推定装置及び基礎部損傷推定プログラムを提供する。【解決手段】基礎部損傷推定装置１００は、建物の各階に設けられた建物センサ１８を用いて平常時建物振動モード及び地震直後建物振動モードを推定する建物振動推定部１０２Ｂと、建物の基礎部の上部に設けられた基礎部センサ２０を用いて平常時基礎部振動モード及び地震直後基礎部振動モードを推定する基礎部振動推定部１０２Ｃと、平常時建物振動モードを用いて地震直後基礎部振動モードを基準化し、基準化された地震直後基礎部振動モードと平常時基礎部振動モードとのモードベクトルの差分が所定差分以上である場合に建物の基礎部が地震による損傷を受けたと推定する損傷推定部１０２Ｄと、を備える。【選択図】図３
