Abstract(s) :

(Anglais) Structural insulated panel (SIP) is mainly used in North America. It is composed of rigid foam plastic insulation glued between two structural skins of wood-based material. These panels are able to bear loads for residential buildings and are used for walls, floors and roofs. The development of a new SIP is studied. The skins are composed of cross-laminated timber (CLT) and the insulation is non-rigid. The mechanical behaviour is preserved thanks to inclined screws that join the wood panels. This new product presents advantages: it could be used for bigger buildings; it could improve the CLT construction by a higher level of prefabrication and a reduction of the wood consumption. In order to understand the mechanical behaviour of this new product, experimental and numerical studies are carried out. The embedment strength of the CLT is measured. These experimentations allow to show the importance of the crossed and glued laminated boards. Different types of panel assemblies are made, their load bearing capacity and their failure mode are presented. As predicted, the screwing angle turns out to be important. The load bearing capacity can be changed by a factor of three and the failure can be ductile or brittle depending on the case.
