The objective of the research work is to investigate a possible twenty storey high office timber building and to discuss about the problem of load transfer and bracing. Considering boundary the design is done according to the significant lateral loads. Therefore the dynamic behaviour due to the load cases wind and earthquake is analysed. In a research approach several possibilities of load bearing, bracing and floor systems are compared. For load bearing systems two dimensional linear or surface elements or a combination of both are practicable. For bracing systems the stiffening with diagonals and the stiffening with rigid frame connections are investigated. The floor structure has various funtions like sound insulation, load bearing and stiffening. On the basis of two examples the different structures are investigated. The first one is a square type partial crosswise stiffened by diagonal elements and the second one is restangular type with rigid connections of cross laminated timber elements in vertical and horizontal direction. The dynamic calculations are carried out by framework software and finite eleement program. Due to the softness of slender multi-storey timber structures the buildings show good behaviour in case of earthquake. Dynamic wind loads have more influence considering Viennese circumstances. For optimal stiffening the bracing system is located in the façade connected by a shear stiff floor structure. Cross lamnated timber panels seem to be efficient solution combining high shear stiffness for bracing, high load bearing capacity and good characteristic values as façade elements might be carried out by simple steel conectors. The behaviour of such connections must bei investigated.
