Public ISBD [article]  inJournal of engineering mechanics > Vol. 133 N°6 (Juin 2007) . - pp.677–687. Titre : Modeling cracking in shell-type reinforced concrete structures Type de document : texte imprimé Auteurs : Wenyuan Wang, Auteur ; Susanto Teng, Auteur Année de publication : 2007 Article en page(s) : pp.677–687. Note générale : Applied mechanics Langues : Anglais (eng) Mots-clés : Concrete structures Cracking reinforced Finite element method Shell Numerical analysis Résumé : A three-dimensional (3D) hypoelastic material model for modeling material properties of cracked reinforced concrete is proposed. Material properties of multidirectionally cracked reinforced concrete are represented by the material properties of intact concrete and a number of uniaxially cracked concrete with their coupling solids. Cracking effects due to multiple nonorthogonal cracks are traced in each uniaxially cracked concrete. Tension softening and aggregate interlock occurring at the crack interface as well as tension stiffening and compression softening initiated in concrete between cracks due to multiple nonorthogonal cracks are all incorporated explicitly. RC panels under in-plane loading and RC slab under pure torsion have been analyzed. The developed 3D hypoelastic material model has been proved to be efficient and effective in modeling the material behaviors of cracked reinforced concrete in shell-type RC structures. The deformational response, the ultimate strength, and failure mode can be captured reasonably well.
