BUILDING EARTHQUAKE RESISTANCE EVALUATION SYSTEM AND BUILDING EARTHQUAKE RESISTANCE EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To perform response analysis of a building, matching to a real condition of a building.SOLUTION: A building safety verification system comprises: a detection part for detecting vibration of a building; a vibration parameter derivation part for deriving a vibration parameter which indicates transfer characteristics of vibration of the building, based on the vibration detected by the detection part; an analysis processing part for analyzing the vibration detected by the detection part, for each position of an analysis object of the building; and a breakage position estimation part for based on the analysis result for each position of the analysis object of the building of the vibration of the building, estimating a breakage state of the building. The vibration parameter derivation part derives the vibration parameter of the building based on vibration data in a first period in which, the vibration detected by the detection part does not contain vibration whose magnitude is equal to or higher than a prescribed value, and the analysis processing part analyzes vibration data in a second period in which, the vibration detected by the detection part contains vibration whose magnitude is equal to or higher than the prescribed value, as an object of analysis, then uses a condition determined based on the derived vibration parameter in the analysis processing, for acquiring displacement or a deformation amount of each position of the analysis object of the building.SELECTED DRAWING: Figure 1
