Abstract

Within a comprehensive research project devoted to analyse the contributing effect of cladding panels on the structural behaviour of steel frames under horizontal loads, a suitable experimental procedure has been set up in order to characterise the main behavioural parameters of specific shear walls. In particular, with regard to light-weight sandwich panels, which are currently used in building as enclosure elements, monotonic and cyclic full-scale shear tests have been performed on both single connection specimens and pin-jointed steel frames branced by infill panels. Such an activity, whose main results are summarised in this paper, firstly provides the experimental evidence as basis for setting up numerical and analytical intepretative models. Besides, it supplies useful information on the possibility to use this panel typology as shear wall components. Finally, it points out how their shear performance can be improved through simple modifications of standard prototypes.

Résumé

Dans le cadre d'un projet de recherche qui analyse les effets des panneaux de façade sur le comportement structurel des cadres en acier soumis à des sollicitations horizontales, il a été défini une méthode expérimentale permettant de caractériser les principaux paramètres du comportement des parois au cisaillement. Notamment en ce qui concerne les panneaux sandwiches légers, souvent utilisés dans les bâtiments comme éléments de façade, des essais au cisaillement monotones et cycliques ont été effectués à échelle réelle, soit sur des échantillons de connexions, soit sur des cadres articulés en acier soutenus par des panneaux. Une telle activité, dont les résultats sont résumés dans cet article, présente tout d'abord les résultats expérimentaux en tant que base d'établissement des modèles d'interprétation numérique et analytique. En outre, l'analyse fournit des informations utiles sur la possibilité d'adopter cette typologie de panneau comme composant de murs de refend. Enfin, elle souligne la façon dont leur performance au cisaillement peut être améliorée par de simples modifications des prototypes d'origine.
