Coupled mechanics - probalistic methodology fof realiability assessment of timber structure with cracks subjected to thermo-visco-hydromechanical

International audience; This study is carried out within the framework of the ANR JCJC CLIMBOIS project which aims is to assess the reliability of timber structures with cracks subjected to thermo-visco-hydro-mechanical (TVHM) from experimental data. The principle is to use coupled mechanics -probabilistic approach to generate database for constructing a Bayesian Network (BN) representing for structural performance. An experiment on a beam Douglas wood exposed to external environment was developed to obtain real data about the variation of temperature and deflections of the beam. These data are introduced into BN for updating structural reliability. The results showed that this methodology is useful for reliability assessment of structures from experimental data.
