모달 변형에너지를 이용한 고층건물의 손상탐지

다국어 초록 (Multilingual Abstract)

In this paper, the effectiveness of a damage detection theory in high-rise building is numerically investigated. An existing theory which uses modal strain energy extracted from the mode shape of structure to localize damage is introduced. A 45-story high-rise buil ding is selected as a target structure. To prove the efficiency of the method, 10 damage scenarios are simulated and the damage indice s are calculated from the mode shape of undamaged and damaged structures. The result shows better performance when using the mult iple mode shapes of structure.
