Ponts et charpentes Résumé : This paper presents a model for fiber-reinforced cementitious composites (FRCCs) based on a cohesive-frictional interface theory. A zero-thickness joint model is formulated for simulating the fracture behaviour of interfaces between the various phases of fiber-reinforced concretes. In particular, the “Mixture Theory” is used for describing the coupled action between concrete and fibers. Numerical analyses have been carried out on both plain concrete and FRCC members. Comparisons between numerical simulation and experimental evidence demonstrate the accuracy and soundness of the proposed formulation.

Shear - flexible steel - concrete composite beams in partial interaction / Enzo Martinelli in Journal of engineering mechanics, Vol. 138 N° 2 (Fevrier 2012) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 138 N° 2 (Fevrier 2012) . - pp. 151-163 Titre : Shear - flexible steel - concrete composite beams in partial interaction : Closed - form "Exact" expression of the stiffness matrix Type de document : texte imprimé Auteurs : Enzo Martinelli, Auteur Année de publication : 2012 Article en page(s) : pp. 151-163 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Steel  Concrete  Composite  beams  Stiffness  Finite  element  method Résumé : This paper presents a theoretical model for analyzing shear-flexible steel-concrete composite beams in partial interaction. Both concrete slab and steel beam are modeled according to Timoshenko’s theory, and a continuous linear-behaving shear connection is considered between the two connected members. Simplified kinematic assumptions have been considered for the displacement fields of the two connected members to derive a model, which is at one time rather general, but even simple enough to be easily handled and actually solved in closed-form. The analytical formulation of both stiffness matrix and vector of equivalent nodal forces is the key achievement of the present paper. They completely define an "exact" finite element for the mentioned model and can be easily employed for carrying out computationally efficient analyses of steel-concrete composite beams looking after the effect of both shear flexibility of the structural members and slips occurring at the interface between the two connected members. Simple applications are finally proposed for demonstrating that the present "exact" finite element can be employed for analyzing shear-flexible steel-concrete composite beams by using just one element-per-member. Thus, it is more efficient than both alternative numerical solutions already available in the scientific literature and commercial finite element packages.
