Estudo da fadiga em articulação de concreto tipo Freyssinet

Abstract

The purpose of this work was to study the behavior of the Freyssinet concrete hinges, used for rail viaducts. We tried to fulfill the conditions for a support of this kind, either in its measures or in its efforts. So we applied to the model milions of cycles of rotations, keeping the axial compression steady. The aim of the notes were actually to verify the possibility of damages to the hinges due to eventual effects of fatigue in the concrete which constitute them.
