This article outlines static and dynamic analyses of the viewing platform in Trzęsacz. The steel construction consists of two parallel lattice girders placed on concrete columns. The elements of the girders are made of tubular profiles. Ultimate limit state and serviceability limit state criteria were fulfilled in accordance with algorithms from Eurocodes. This paper also presents an analysis of the platform’s dynamic responses from rhythmical motion caused by human activity. The results of these calculations were checked with the comfort levels of people standing in the platform during the vibrations. Robot Structural Analysis Professional was used for the linear load case of static analysis and modal analysis.
