Abstract
(EN) The present invention relates to a structure life evaluation method and evaluation system. The structure life evaluation method may comprise the steps of: preparing a structure to be measured; measuring the calorific value or endothermic value of the structure to be measured; measuring the entropy reduction amount for the structure to be measured by using the measured calorific value or endothermic value; and predicting the remaining life of the structure to be measured from the measured entropy reduction amount.
(FR) La présente invention se rapporte à un procédé d'évaluation et à un système d'évaluation de durée de vie de structure. Le procédé d'évaluation de durée de vie de structure peut consister : à préparer une structure à mesurer ; à mesurer la puissance calorifique ou la puissance endothermique de la structure à mesurer ; à mesurer la quantité de réduction d'entropie de la structure à mesurer à l'aide de la puissance calorifique ou de la puissance endothermique mesurée ; et à prédire la durée de vie restante de la structure à mesurer à partir de la quantité de réduction d'entropie mesurée.
(KO) 본 발명은 구조물의 수명 평가 방법 및 평가 시스템에 관한 것으로, 구조물의 수명 평가 방법은 상기 피측정 구조물을 준비하는 단계; 상기 피측정 구조물의 발열량 또는 흡열량을 측정하는 단계; 상기 측정된 발열량 또는 흡열량을 이용하여 상기 피측정 구조물에 대한 엔트로피 감소량을 측정하는 단계; 및 상기 측정된 엔트로피 감소량으로부터 상기 피측정 구조물의 잔여 수명을 예측하는 단계를 포함할 수 있다.
