A novel hybrid system with RC-encased steel joists / Claudio Amadio in European journal of environmental and civil engineering, Vol. 15 N° 10 (Octobre 2011) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 15 N° 10 (Octobre 2011) . - pp. 1433-1463 Titre : A novel hybrid system with RC-encased steel joists Titre original : Un nouveau système hybride composé de poutres en treillis d’acier noyées dans le béton Type de document : texte imprimé Auteurs : Claudio Amadio, Auteur ; Lorenzo Macorini, Auteur ; Sveva Sorgon, Auteur Année de publication : 2012 Article en page(s) : pp. 1433-1463 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Composite  structures  RC  encased  steel  joist  Beam-to-column  connections  Shear  resistance  mechanism  Analytical  models  for  shear  and  bending  resistance Résumé : The paper presents the main results of an experimental and numerical study on a novel structural frame system, which employs RC encased steel joist beams and columns. An accurate 3D numerical model has been used to represent the resistance mechanisms in beams and beam-to-column connections. Experimental and numerical outcomes have been employed to develop suitable analytical models to be used in practical design. In particular, the beam flexural response has been investigated, providing a simple relationship for the flexural rigidity at different load levels. Capacity models have been then proposed for the bending and shear resistance of partially and fully-encased beams, and for exterior beam-to-column joints.
