The unconventional tribune profiles in architectural designing of stadiums

Abstract

One of the key issues in designing of stadiums is to define the profile of the stands. By this term is meant a contour of the vertical cross-section of the tribunes, which is carried out in a plane perpendicular to the edges of the rows of seats. Such a profile reflects the spatial relations between theoretical points of the eye, arranged in individual rows, specifying their horizontal and vertical displacement relative to neighbouring points. It also allows you to determine the extent of visibility of the arena for each of them, using graphs of visibility. But it is also determined by considerations of communication links between the individual rows of seats by using the stairs. These stairs must however be adapted to the human motoric ability. Today, due to economic reasons, the designers completely abandoned the use of curved profile, replacing it with a sloping straight line. Existing standards limit this slope up to 35°. Reminiscent of the curved profiles are currently used broken linear profiles, as the continuous or balcony types. The author takes many years of research on the designing of modern stadiums, especially in shaping large spectator zones. Presented in this article unconventional solutions of modern stadium stands profiles are the result of these studies. These proposals improve much the parameters of visibility, comfort and safety of spectators. They contribute as well in the development on the field of stadiums designing, bringing a new values, such as quite new architectural forms in shaping interiors of these objects.
