Title:
METHOD FOR DIAGNOSING AND EVALUATING STRUCTURE BASED ON ALWAYS FINE MOVEMENT OF STRUCTURE
Document Type and Number:
Japanese Patent JP2021021746
Kind Code:
A
Abstract:
To provide a method for diagnosing and evaluating a structure based on the always fine movement of the structure, which is different from a conventional method in which soundness and safety of the structure is achieved by directly applying an external force or the like to an object, and earthquake resistance and soundness of the structure and the effect of a countermeasure work and a reinforcing work can be inexpensively and quickly diagnosed and evaluated.SOLUTION: Disclosed is a method for evaluating performance of a structure by the always fine observation, which includes the steps of: constantly observing a fine observation history at the same time at a plurality of observation points in the structure; calculating an estimated value of an index used for an earthquake resistant design of the structure using the root mean square (RMS) of these time histories; and performing evaluation of the earthquake resisting performance based on the observation of the structure using a ratio to a value of the index used at a point of time when this value is designed.SELECTED DRAWING: Figure 4
