Modern architecture with the renewable material wood leads to impressive and demanding timber structures with high requirements for planning, production, logistics, commissioning, and use. Quality assurance during the construction and durability during the operational phase is crucial. The realistic estimation of the risks for all timber structure elements during the construction and operation phase, the risk of cracking, shape stability of the cross sections and long-term performance of connections are important points. With an increasing height of timber-buildings, the requirements of durability are rising as well. To avoid damages, the special characteristics of timber as a building material should be considered comprehensively. To evaluate, which topics regarding the durability are most relevant for the design of tall timber-buildings, the definition according to EN 1990 is given: Durability means the ability of a structure or structural member to satisfy, with planned maintenance, its design performance requirements over the design service life
