Assessment of an industrial pavement via the impact acoustics method / Roberto Felicetti in European journal of environmental and civil engineering, Vol. 14 N° 4 (Avril 2010) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 14 N° 4 (Avril 2010) . - pp. 427-439 Titre : Assessment of an industrial pavement via the impact acoustics method Type de document : texte imprimé Auteurs : Roberto Felicetti, Auteur Année de publication : 2011 Article en page(s) : pp. 427-439 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Delamination  Impact  acoustics  Hammer  tapping  Pavements Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : Industrial pavements often represent a critical issue in Civil Engineering. Shrinkage strain, excessive deflection, fatigue loading, incompatibility among different concrete layers are some common problems which may lead to an extensive damage in this type of structure. Such inconveniences usually involve quite large areas, calling for efficient Non-Destructive techniques in order to perform a thorough inspection of the pavement conditions. In this paper the impact-acoustic technique has been regarded as a method for detecting the delamination occurring under the abrasion-resistant top coating of concrete ground-slabs. The implementation via affordable tools for digital audio recording, the proper processing of the audio files and the procedure for drafting the damage maps are discussed in the paper with reference to the case study of a warehouse building.

Friction dissipative devices for cladding panels in precast buildings / Liberato Ferrara in European journal of environmental and civil engineering, Vol. 15 N° 9 (Novembre 2011) 

Public ISBD [article]  in European journal of environmental and civil engineering > Vol. 15 N° 9 (Novembre 2011) . - pp. 1319-1338 Titre : Friction dissipative devices for cladding panels in precast buildings : An experimental investigation Titre original : Dispositifs amortisseurs par frottement pour panneaux de revêtements de bâtiments en béton préfabriqué. Une recherche expérimentale Type de document : texte imprimé Auteurs : Liberato Ferrara, Auteur ; Roberto Felicetti, Auteur ; Giandomenico Toniolo, Auteur Année de publication : 2012 Article en page(s) : pp. 1319-1338 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Friction  dampers  Precast  r/c  buildings  Earthquake  design Index. décimale : 624 Constructions du génie civil et du bâtiment. Infrastructures. Ouvrages en terres. Fondations. Tunnels. Ponts et charpentes Résumé : This study focuses on the design and experimental assessment of the behaviour of friction dampers to be used along the edges of cladding panels in precast r/c buildings. The concept and design of such devices is based on a no-slip requirement under wind and moderate earthquake loadings, while allowing large displacements and consequent significant energy dissipation due to friction for higher intensity earthquakes. Elements were custom-built by assembling, through bolted connections, of steel profiles, in case with interposed brass plates, to obtain a more stable response under cyclic loadings. An experimental investigation has been performed in order to characterize the behaviour of these devices under cyclic loadings, including the displacement rate effect. The work is intended as prodromal to a wider assessment of the seismic behaviour of precast r/c structures with friction damping panel-edge connections.
