With means of theoretical and empirical research this master thesis main question “Which effects do combustible structural elements of high-rise buildings have on the fire risk?”. The theoretical part contains definitions of research relevant terms. Thereafter, the paper focuses on current fire protection regulations and their application problems in novel constructions. This is followed by the current state of research to elaborate the basics and characteristics of fire risks. Therefore, the findings of the research in relevant literature will be summarized and considered critically, as well as own ideas and findings are presented. The empirical part deals with the central research question. For this purpose, the fire protection regulations for skyscrapers in Vienna are assessed by the fire risk assessment method F.R.A.M.E according to . Subsequently, a variant with visible solid wood construction is presented and subjected to a safety assessment. In addition, proposals for suitable compensatory measures will be developed. The study shows that timber high-rise buildings have the same level of fire safety as conventional non-combustible constructions.
