Influence de la température sur les assemblages bois

Abstract : The more generalized use of wood for building raises concern for fire safety. The current standards require the structure stability for a minimum time to ensure the building evacuation and the fire fight. Considering that the fire endurance of wood is well-known, the stability requirement is mainly reduced to the understanding of the behaviour of wood joints on fire. The aim of this work is to study the behaviour of single-dowel timber joints and it is divided into three parts. The first part is a study of the influence of temperature on the modulus of elasticity and on the embedding strength in a range between 20 and 300°C. In the second part the wood charring and the influence of a metallic dowel embedded in wood, is studied. In the third part, the fire behaviour of single-dowel wood joints is tackled. The first two studies have provided mechanical and thermal data to allow the development of a model to simulate the joint behaviour and its fire endurance before fracture.
