DAMAGE DETECTION METHOD FOR STEEL BUILDINGS BASED ON ACCELERATION INTEGRATION AND LOW CYCLE FATIGUE CURVE APPLIED TO SHAKING TABLE TEST DATA

Abstract

As a damage detection method for steel buildings after an earthquake, an evaluation method of integrating acceleration records and calculating damage level to beam end using low cycle fatigue curve is investigated. The applicability is examined by using this method to shaking table test data of a full-scale three-story steel structure. In the case of a large amplitude shaking test, fracture of the bottom beam flange can be predicted by this method.
