Natural constructions rate as optimal regarding their form, function and strength. Investigations of optimization strategies in nature leaded to findings and methods , which evoke growing interest in the technical fields and are subsumed today under the term bionic. Solutions based on natural examples do not rest upon the direct usage of these concepts and constructions but on the transfer and adaptation
of their principles. Thus, the usage of curved or branched tree sections as for example in the former ship building trade is not considered anymore. The progress in the field of the information technology, especially the computer aided construction and production as well as the photogrammetry, pave the way first time for an industrial control of complex structures with smallest lot sizes, from which new approaches in civil engineering and architecture follow. In this context, the structural behaviour of codominant branches of deciduous trees, especially ash, is investigated. A new connection concept is motivated in association with textile reinforced wooden tubes, which is treated experimentally and numerically.
