BUILDING SOUNDNESS DIAGNOSTIC SYSTEM
To detect deformation of a building based on the displacement of a floor and a ceiling thereof in diagnosing soundness of the building against the shaking of an earthquake so that it is possible to diagnose the soundness of the building without being restricted by an installation location of a displacement sensor.SOLUTION: A building soundness diagnostic system includes: accelerometers 31 each installed on floors 21 (22) and ceilings 22 of a high-rise building 2, detecting acceleration of seismic vibration of each of the floor 21 (22) and the ceiling 22, and outputting a detection signal by wireless communication; a receiver 32 installed in the same layer as each acceleration sensor 31 in the high-rise building 2 and receiving the detection signal of each acceleration sensor 31 by wireless communication; a computer 33 (34) diagnosing the building soundness that receives a signal of the receiver 32 and integrates acceleration time history data twice to obtain displacement time history data, and calculates an interlayer deformation angle of the high-rise building 2 based on the displacement time history data.SELECTED DRAWING: Figure 3
【課題】地震の揺れに対する建物の健全性を診断するものにおいて、建物の変形を床と天井の変位に基づいて検出することにある。それにより、変位センサの設置場所に制約を受けることなく建物の健全性診断を可能とする。【解決手段】高層ビル２の床２１（２２）及び天井２２にそれぞれ設置され、床２１（２２）及び天井２２それぞれの地震振動の加速度を検出して検出信号を無線通信により出力する加速度センサ３１と、高層ビル２内で各加速度センサ３１と同じ層内に設置され、各加速度センサ３１の検出信号を無線通信により受ける受信機３２と、受信機３２の信号を受けて加速度時刻歴データを２回積分して変位時刻歴データを求め、この変位時刻歴データに基づいて高層ビル２の層間変形角を算出し、建物の健全性を診断するコンピュータ３３（３４）とを備える。【選択図】図３
