Modelling of three-dimensional crack patterns in deep reinforced concrete structures

Résumé

The analysis of the crack width variation within the depth of a reinforced concrete structure is difficult to perform. No experimental measurement can give a non-intrusive, three-dimensional and quantitative description of cracking. Moreover, most of the design codes cannot give a predictive measurement of the full cracking pattern. This paper applies a global/local computational strategy in order to quantify the cracking behaviour of reinforced concrete structures. A continuous damage model is used to perform a full resolution at the global scale. Then a reanalysis of the damaged zones is performed at the local scale with a discrete element model. This strategy has proved its efficiency for the study of cracking of small laboratory specimens made in concrete. The extension to massive reinforced structures is achieved here and numerical results on the influence of three-dimensional effects and rebars on cracking are given.
