Title:
DEVICE AND METHOD FOR EVALUATING ASEISMATIC PERFORMANCE OF BUILDING
Document Type and Number:
Japanese Patent JP3952851
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To quickly and objectively determine residual aseismatic performance of a building after an earthquake occurs, to properly manage the damaged building, to reduce a secondary disaster against an aftershock, and to reduce the number of an unnecessary evacuees.
SOLUTION: Each measured acceleration value measured by acceleration sensors 10a, 10b provided in a base part and an upper story of the building is second-order- differentiated to calculate an absolute displacement in a measuring point, a vibration mode of the building is assumed to calculate a relative displacement and an absolute acceleration in the each floor of the building, and a representative displacement for representing a response deformation amount of the building and a representative acceleration for representing a response acceleration of the building are calculated based on values thereof to find a performance curve of the building. On the other hand, an acceleration response spectrum and a displacement response spectrum are calculated as input earthquake movement input into the building with the measured acceleration value in the base part so as to find a requirement curve of the building. The performance curve is compared with the requirement curve to determine the residual aseismatic performance of the building.
