To provide a soundness evaluation system capable of improving accuracy of an estimate indicating a response of a building based on a building model for estimating responses of buildings, and a soundness evaluation method.SOLUTION: A soundness evaluation system 1 for evaluating soundness of a building on the basis of a building model for estimating responses of buildings comprises a plurality of sensors Sn which detect an acceleration of a building B, and an arithmetic logical unit 14 which calculates a primary natural period of the building on the basis of detection values of the plurality of sensors, and updates parameters on distribution of masses and rigidity included in the building model on the basis of the primary natural period.SELECTED DRAWING: Figure 1 【課題】建物の応答を推定する建物モデルに基づく建物の応答を示す推定値の精度を向上することができる健全性評価システム及び健全性評価方法を提供する。【解決手段】建物の応答推定を行うための建物モデルに基づいて前記建物の健全性を評価する健全性評価システム１であって、前記建物Ｂの加速度を検出する複数のセンサＳｎと、前記複数のセンサの検出値に基づいて、前記建物の１次固有周期を算出し、前記１次固有周期に基づいて、前記建物モデルに含まれる質量及び剛性の分布に関するパラメータを更新する演算部１４と、を備えることを特徴とする、健全性評価システムである。【選択図】図１
