Résumé

Afin de mesurer les déformations internes dues à un effort de compression uniaxiale, on a noyé dans le béton lors de son coulage une jague de déformation à résistance électrique. On donne des précisions sur la méthode de préparation de la jauge, sur sa mise en place et sur l’étude comparative qui a été faite entre les déformations mesurées à l’intérieur et à la surface de l’éprouvette. On a constaté que les déformations internes avaient des valeurs supérieures aux déformations superficielles.

Summary

An electrical resistance strain gauge was embedded in the concrete during its casting to measure the internal strains due to uniaxial compressive loading. Details are given of the method of preparation of the strain gauge, embedding the strain gauge and comparisons have been made between the strains measured inside and on the surface of the specimen. It has been found that the internal strains were more than the surface strains.
