WORKSHOP de l’ANR RECAP,

20 octobre 2017, 9h30-18h,

Laboratoire de géologie de l’ENS, salle E314 (24, rue Lhomond 75005 Paris)

Dans le cadre du programme ANR RECAP, les laboratoires d’archéologie (AOROC) et de géologie de l’Ecole normale supérieure, l’Institut de radioprotection et de sûreté nucléaire et l’Association française du génie pararismique et organisent un workshop sur les techniques de maçonnerie face aux séismes, de l’Antiquité à nos jours : perspectives d’études pluridisciplinaires.

Explorer les caractéristiques du patrimoine bâti face aux tremblements de terre présente un enjeu crucial dans  les zones à risque. Complexe et encore largement méconnu, le comportement des maçonneries, qui  constituent une des techniques de construction les plus traditionnelles depuis l’Antiquité, mérite d’être considéré à part entière. Ce sera l’objectif de ce workshop international, conçu comme un bilan des méthodes  d’analyse. Il réunira archéologues, sismologues,  ingénieurs des structures et architectes. Ces différents  spécialistes croiseront leurs approches afin de dessiner de nouvelles perspectives d’étude et de conservation  des bâtiments en maçonnerie.

Inscription gratuite et obligatoire sur le site : http://www.geologie.ens.fr/workshop

Organisation : Didier Combescure (AFGP), Hélène Dessales (ENS, AOROC-UMR 8546), Maria Lancieri (IRSN), Hélène Lyon-Caen (ENS, Laboratoire de géologie-UMR 8538)

In the framework of the ANR RECAP, the laboratories of archaeology (AOROC) and geology of the Ecole normale supérieure (UMR 8538, 8546), the Institut de radioprotection et de sûreté nucléaire and the Association française du génie parasismique organize a workshop on Masonry techniques in the face of earthquakes, from Antiquity to the present: prospects for multidisciplinary studies

Exploring the characteristics of heritage buildings in the face of earthquakes presents a crucial issue in risk-prone areas. Complex and still largely ignored, the behavior of masonries, which constitute one of the most traditional building techniques since Antiquity, needs to be focused. The aim of this international workshop is  to assess the various methods of analysis. It will bring together archaeologists, seismologists, structural engineers and architects. These various specialists will cross their approaches in order to define new directions for the study and conservation of masonry buildings.
