Cracking of reinforced concrete
The laboratory deals with the issues linked to the cracking of reinforced concrete, in particular the calculation of crack opening and crack spacing based on some damage models including mechanical stresses. The aim is both the preservation of major structures stocks (road structures) and the durability of critical structure for which the question of structural safety is crucial (nuclear structures). The development of some damage models and their links with cracking of concrete are also applied for the durability analysis of reinforced concrete structures subject to the corrosion induced by carbonation or chloride ingress. The consideration of an advanced damage model is an asset to accurately model the concrete cracking under the expansion effects of corrosion products, as well as the degradation of the mechanical properties of the bond at the steel/concrete interface.
