Pathologies des structures en bois : analyse des caractéristiques physiques et mécaniques des collages structuraux pour la restauration des charpentes

Abstract : The work is dedicated to the restoration of old timber structures. The scope is the analysis of physical and mechanical characteristics of structural glued joints, for the development of glues which are more "compatible" with wood and more performant. A bibliographic study describes the restoration techniques, the structural pathologies, the design and installation aspects. The research is finalised to the physical characteristics which are more relevant for design. The analysis is conducted with specifically-developed methodologies, for the description of significant causes and effects. Exploitation of results comprises: the definition of an objective "compatibility coefficient" between glue and wood ; a re-formulation of the Eurocode 5 design equation, with the integration of a "joint thickness" factor; an example of design and installation. The results are already being used by Mapei spa as a reference for formulation improvement, and are the basis for new standards (CEN/TC193/SC1).
