Role of test conditions on the pull-out resistance of reinforcements

Abstract

The role of test conditions on the pull-out resistance of reinforcements is studied based in the results of ten pull-out tests carried out in a large dimension equipment. Toe materials used are a granular soil and a HDPE uniaxial geogrid and the analysed parameters are the specimen length and width, the soil height placed around the specimen and the existence of a sleeve in the frontal wall of the box. Some conclusions are written, particularly in what concerns the validity of reinforcements pull-out resistance measured by pull-out tests carried out with different test conditions.
