PROBLEM TO BE SOLVED: To provide a generally applicable method for diagnosing the safety of a building after an earthquake occurrence.;SOLUTION: The safety diagnostic device includes: an eigenvalue analysis unit for performing an eigenvalue analysis, using a response value obtained from a sensor and the mass of a predetermined building, and determining the value of the rigidity of the building as well as determining an eigenmode and a participation function based on the combination of the mass and the value of the rigidity; an input value estimation unit for determining an input value of an earthquake wave, using a transfer function obtained from a natural frequency estimated with the response value and from the participation function, and the response value; a response value estimation unit for determining an absolute acceleration response by adding a relative acceleration response obtained by multiplying the difference between the waveform of each eigenmode of the response value obtained using the transfer function and the input value by an eigenmode shape, to the input value; and a safety diagnostic unit for integrating the absolute acceleration response and determining the safety of a structure based on an interlayer deformation angle obtained by an absolute displacement obtained for each floor of the structure and the height of floors of the structure.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2018,JPO&INPIT
