This paper presents general remarks on the development of timber
structures as a result of technological changes. It discusses drawbacks
of wood with respect to structural application. Shear and transversal
strengths are very low due to the anisotropy of wood. Various
techniques are applicable to cope with this drawback. This paper
presents the reinforcement by means of tailor made textiles as
comprehensive technology to deal with this kind of difficulties in many
design situations. Particular importance is attached to the material
productivity during the transformation of raw wood into structural
cross sections. It is shown that cut offs in the sawmill and the
predominating full section lead to a poor use of the material compared
to technical profiles. A new understanding of the wood as a cellular
solid is presented that allows a thermo-hygro-mechanical forming of
cross sections from solid wood panels.
