BUILDING DAMAGE INTENSITY ESTIMATING SYSTEM, AND METHOD

摘要

PROBLEM TO BE SOLVED: To reduce the cost of estimating the intensity of damage to buildings having suffered an earthquake.SOLUTION: A building damage intensity estimating system comprises a building damage intensity estimating device 1 and an earthquake sensor 20 installed on the foundation ground surface of a building 2. The building damage intensity estimating device 1 is equipped with a designed building model input unit 10 that inputs a designed building model mathematically expressing earthquake-caused motions of the building 2 derived on the basis of structural design parameters extracted from design drawings and specifications on the building 2; an earthquake response analyzer 11 that inputs ground motion acceleration measured by the earthquake sensor 20 during an earthquake into the designed building model to analyze the responses of the designed building model to the earthquake; an earthquake/motion information calculator 12 that calculates earthquake information and motion information indicating the motions of the building caused by the earthquake by using the results of the earthquake response analysis and the ground motion acceleration; and a damage intensity estimator 13 that estimates the intensity of the damage to the building by using the earthquake information and the motion information after the earthquake is over.SELECTED DRAWING: Figure 1
