A Modular Timber Construction System of Hollow-Box Elements

Timber hollow-box constructions made with solid wood planks are well established as suspended floor structures or roof structures. The application as wall construction is neither known nor used in multi-story timber buildings. A comprehensive timber construction system, as hollow-box constructions, which can be used in residential houses as well as multi-story buildings was developed, was optimized for the “Minergie-Standard” and will be established. Furthermore, an organizational and cost-efficient definition of a new business model allowing smaller timber businesses access to the residential building market. Finally the structural and failure behavior as well as the load capacity was investigated and compared by numerical and experimental tests. Due to the glued box-systems, the elements show a very stiff behavior with a dominant failure in shear which can be predicted very well easily.
