To solve the problem in which, when the mass of an object charging a load to a structure is unknown, the soundness or the like of the structure cannot be accurately analyzed.SOLUTION: The analysis device includes: a data acquisition unit for acquiring displacement data and acceleration data of a structure synchronously measured in the existence of a vibration source having an unknown mass; and an analysis unit for analyzing the soundness of the structure on the basis of the synchronously measured displacement data and acceleration data. The analysis method includes a step of acquiring the displacement data and acceleration data of the structure synchronously measured in the existence of the vibration source having the unknown mass; and a step of analyzing the soundness of the structure on the basis of the synchronously measured displacement data and acceleration data.SELECTED DRAWING: Figure 5 【課題】構造体に荷重を与える物体の質量が不明の場合、構造体の健全性等を正確に解析することができないこと。【解決手段】解析装置は、質量が未知の振動源の存在下で同期測定された構造体の変位データ及び加速度データを取得するデータ取得部と、同期測定された変位データ及び加速度データに基づいて、構造体の健全性を解析する解析部とを備える。解析方法は、質量が未知の振動源の存在下で同期測定された構造体の変位データ及び加速度データを取得する段階と、同期測定により得られた変位データ及び加速度データに基づいて、構造体の健全性を解析する段階とを備える。【選択図】図５
