Experimental Investigation of the Creep-Damage Interaction Effect on the Mechanical Behaviour of Hardening Concrete
The creep behavior of concrete structures at long term depends on the initial state and therefore on an eventual damage of the main material. Most studies were interested in creep phenomenon of mature concrete while a few works were carried out on young concrete. However, the concrete structures may be solicited earlier as the tensioning of the pre-stress cables induces an early creep and an eventual cracking, thus reducing the structure capacity at the long term. An original device for creep tests has been developed to follow the evolution of the displacement, the force and the crack opening during creep since early ages for concrete beams. Creep tests were performed on concrete beams aged of 24h during 28 days. Results show that creep influences the rigidity and the strength when the load-to-strength ratio is maintained constant and if the beam is damaged before the creep test.
