Abstract
W artykule przedstawiono możliwość określenia nośności zamodelowanego elementu betonowego z imperfekcją materiałową w postaci strefy słabego betonu, o obniżonych parametrach materiałowych. Wykonano badanie tomografem ultradźwiękowym na elemencie betonowym w celu dokładnego zlokalizowania słabej strefy betonu. Na podstawie otrzymanych wyników wykonano symulację zniszczenia próbki w programie ABAQUS. Pozwoliło to na dokładne określenie stopnia osłabienia konstrukcji.
Ultrasonic tomography and FEM for evaluation of load capacity of concrete element
Abstract
The article presents possibility to determine the bearing capacity of the concrete element contains a zone of lower parameters of materials. Examination was done on the concrete element using ultrasonic tomography in order to locate accurately the weakened zone. On the basis of the results failure simulation at ABAQUS program was performed. This allowed to accurate determination of the degree of weakening of the structure.
