Résumé
Engineers need confidence in normative standards to design timber structures. Structural design is performed to ensure safety issues and answer qualitative constructions regarding to an economic competitive objective. In order to improve and provide well matched normative rules and wood material behaviour we performed laboratory creep experiments to quantify and describe the kinetics of wood material facing hygro-mechanical history. Furthermore it allows a direct comparison with deformation modification factors of EN1995 regarding an increase of structural longevity of timber structures.
