Sensibility Analysis of Traditional Span Frame
This article deals with the restoration of the wooden frame of the Notre-Dame de Paris Cathedral as part of a scientific project after the 2019 burning. The purpose is to conserve the architectural heritage while ensuring the craftsmanship of the medieval age as described in [1], by Thibaut, Caré and Maurin in 2022. In this context, we have reproduced a part of the timber frame on the basis of the original schemes of the nave. Through an in-situ monitoring, this structure represents a study case in order to provide data relative to the kinetics of displacements of this structure composed of green oak. These informations allow to evaluate the global behaviour of the structure and its vulnerability by taking several deformability sources into account. A numerical bar model has been developed by using finite element software, like in the article [2] by Vannucci. P in 2021, to analyse the sensibility of material properties and geometry with data identified experimentally. We have also performed a retro-analysis focused on the axial stiffness of each connection in the model, by fitting data to reproduce the real displacements measured from static tests realized on the wooden frame. Similarly to the full scale tests performed on the article [3, 4] or [5], from full scale tests in-situ, we examine the effects of static vertical forces involving bending moment of the principal beams and including the influence of the scale factor and the global effects of this traditional timber frame. Furthermore, we carried out an experimental campaign consisting of tryout press on different traditional types of joints. The goal was to characterise their stiffnesses and their specific failure modes using images correlation like in the article [6] by Koch and Eisenhut in 2013. Concomitantly, numerical simulation are developed in order to investigate the dependence of the stiffness with contact gaps between the pieces, which is relative to the know-how of the carpenter and moisture content variations.
