Abstract: Within the CEOS.FR national research project, several experiments on massive concrete structures were conducted in order to improve the knowledge on the cracking phenomenon and, at last, to provide the designers with reliable crack design codes, able to give a reasonable appreciation of crack width and spacing for theses structures as well as for classical ones. In this paper, experiments where deformations at early age are restrained are presented. An example of the evolution of temperature, strains and forces for the RG8bis experiment is given. A first analysis of the cracking process shows that the cracks could appear for stresses below the tensile strength.
