Zusammenfassung:PROBLEM TO BE SOLVED: To provide a technology for making it possible to appropriately detect, with a simple configuration, a location where the magnitude of vibration transmitted between an upper structure and a lower structure of a structure is larger than a certain magnitude.SOLUTION: A structure includes an upper structure mounted on a lower structure through a bearing. A damper 5 includes one end in the axial direction attached on the upper structure side of the structure and the other end in the axial direction attached on the lower structure side of the structure. A sensor node 1 detects whether or not the amount of expansion/contraction in the axial direction of the damper 5 has exceeded a predetermined fixed amount. A report device 2, when the sensor node 1 detects the amount of expansion/contraction in the axial direction of the damper 5 having exceeded the predetermined fixed amount, outputs the detection result.SELECTED DRAWING: Figure 1 【課題】構造物における上部構造と下部構造との間で伝達された振動がある程度の大きさを超えた箇所を簡単な構成で適正に検知することができる技術を提供する。【解決手段】構造物は、上部構造を下部構造の上に支承を介して載置している。ダンパ5は、軸方向の一端が構造物の上部構造側に取り付けられ、軸方向の他端が構造物の下部構造側に取り付けられている。センサノード1は、ダンパ5における軸方向の伸縮量が予め定めた一定量を超えているかどうかを検知する。報知装置2は、センサノード1によってダンパ5における軸方向の伸縮量が予め定めた一定量を超えたことが検知された場合、その旨を出力する。【選択図】図1
