Displacement method for the long-term analysis of steel-concrete beams with flexible connection / Francesca Giussani in Journal of structural engineering, Vol. 136 N° 3 (Mars 2010) 

Public ISBD [article]  in Journal of structural engineering > Vol. 136 N° 3 (Mars 2010) . - pp. 265-274 Titre : Displacement method for the long-term analysis of steel-concrete beams with flexible connection Type de document : texte imprimé Auteurs : Francesca Giussani, Auteur ; Franco Mola, Auteur Année de publication : 2011 Article en page(s) : pp. 265-274 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Composite  steel-concrete  beams  Deformable  connectors  Creep  Shrinkage  Prestressing  Imposed  displacements Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : The long-term behavior in the service stage of continuous composite steel-concrete beams with deformable connectors subjected to uniaxial bending and axial load is presented. The problem is dealt with by recurring to the displacement method, assuming the bending curvature and the longitudinal deformation as unknowns, and obtaining a system of differential and integro-differential equations. The results are compared with literature experimental tests. A case study is then discussed, referring to a continuous beam subjected to permanent and variable loads, to concrete shrinkage, and to a vertical displacement imposed to the central support or to the prestressing of the central part of the beam.
