Timber lightweight (wood chip)

Eigenprojekt
Timber-lightweight (wood chip) concrete composite structures represent a recent technique used both in existing timber structures and in new constructions for strength and stiffness upgrading. Advantages of composite timber-lightweight (wood chip) concrete structures can be found in facts that the load bearing capacity of, for example, floors can be doubled and its out-of plane stiffness improved more times, serviceability conditions are better satisfied, sound insulation is improved, fire resistance too, vibrational effect in the buildings thanks to concrete decreases and the self-weight of the whole structure is less than self-weight concrete type structure or steel type structure for the same constructional work. Timber-lightweight concrete composite systems form a low-cost solution to renovate existing timber floors. The increased stiffness and strength are such that higher floor loads are permissible or decreased deflections are obtained. The structural behavior of timber-lightweight concrete composite members is governed by the shear connection between them. The key objective of this research project is to provide and facilitate new possibilities for timber-lightweight concrete structures in construction. The use of timber-lightweight concrete products is to be supported and stimulated by comprehensive and scientifically robust background data, which is presented in user-friendly and adapted tools for engineers. The research project has three aims - Combining timber and concrete in a new type of composite material and using the best properties of both materials, the high tensile strength of timber and the high compressive strength of concrete, depending on different building conditions. - Innovation applies to both, development in materials and building elements, as well as design approaches (design concepts for load-bearing timber-lightweight concrete structures). - Provide practical, well presented information for designers and architects in a comprehensive handbook.
