Assistant Professor, Department of Mechanical Engineering

Assistant Professor Daiki Tajiri and Professor Shozo Kawamura of the Machine Dynamics Laboratory, Technology Department of Mechanical Engineering, Toyohashi University have developed a simple method that identifies the rigidity deterioration of a building’s columns based on only the frequency response of force measured using an inertial shaker installed on the top floor of the building. This method enables the diagnosis of abnormalities in the entire building without requiring acceleration sensors and other equipment on multiple floors, as in the case of conventional methods; in fact, it requires only force sensors.
