部位の影響度推定方法、被災度評価方法、及び、部位の影響度推定装置
Document Type and Number:
Japanese Patent JP7283656
Kind Code:
B2
Abstract:
To estimate an effect-degree of a part more accurately.SOLUTION: A pushover analysis in a model before damage before input of external force to a building is performed. Stress/deformation states of: a partial pin model of the building assuming one of damaged parts identified by the pushover analysis as a pin part; and the model before damage are replaced with an aggregate model aggregating columns provided to each layer as one column in each layer of the building. An interlayer deformation angle of each layer of the building in the aggregate model of the partial pin model is calculated, on the basis of the layer where the pin part belongs and the proof stress of the pin part and the stress and deformation of each layer in the aggregate model of the model before the damage. A response acceleration, a response displacement and a damping constant at a safety limit in the partial pin model are determined on the basis of the calculated interlayer deformation angle. A holding earthquake resistance performance index of the partial pin model is calculated, and an effect-degree is estimated on the basis of the calculated holding earthquake resistance performance index.SELECTED DRAWING: Figure 9
