(KO) 충격에 의하여 발생하는 응력파속도를 이용한 부착식 텐던의 긴장력 평가 방법
Abstract: front page image
(EN)The present invention relates to a method for evaluating prestress force of a bonded tendon. The present invention comprises a first step which excites a prestressing strand of a bonded tendon with an excitation hammer, a second step which measures an acceleration response signal generated in the prestressing strand and receives the signal through a data logger, and a third step which measures stress wave velocity based on the acceleration response signal received from the data logger, and evaluates the prestress force of the bonded tendon based on the measured stress wave velocity in a control unit.
(FR)La présente invention concerne un procédé permettant d'évaluer la précontrainte d'un câble adhérent. Le procédé de l'invention comprend une première étape consistant à exciter un toron de précontrainte d'un câble adhérent avec un marteau d'excitation ; une deuxième étape consistant à mesurer un signal de réponse d'accélération généré dans le toron de précontrainte et à recevoir le signal par l'intermédiaire d'un enregistreur de données ; et une troisième étape consistant à mesurer une vitesse d'onde de contrainte sur la base du signal de réponse d'accélération reçu de l'enregistreur de données, et à évaluer la précontrainte du câble adhérent sur la base de la vitesse mesurée de l'onde de contrainte dans une unité de contrôle.
(KO)본 발명은 부착식 텐던의 긴장력 평가 방법을 개시한다. 본 발명은, 가진망치로 부착식 텐던의 강연선을 가진하는 제 1 단계와, 가속도계로 상기 강연선에서 발생하는 가속도 응답신호를 측정하고 데이터로거를 통하여 수신하는 제 2 단계와, 상기 데이터로거로 수신된 상기 가속도 응답신호를 근거로 응력파속도를 산출하고, 산출된 상기 응력파속도를 근거로 상기 부착식 텐던의 긴장력을 제어부에서 평가하는 제 3 단계를 포함한다.
