The aim of this contribution is a form-finding process. It is the problem of initial pre-stressed shape generation of membrane constructions. The contribution deals with specific aspects of this process and the necessity of introducing stabilization with regard to its practical application. Individual examples will show the results of methods described in this paper.
The aim of this paper is an introduction to a very specific area of civil engineering, which is known as tensile structures (structures acting only in tension). These structures are associated with unique aspects of their design. As a result of practically zero bending stiffness, it is not possible to separate the shape and the static analysis of these structures. Shape generation is the aim of the process well known as form-finding. As a consequence of these and many other facts, it is necessary in this case to use a special way of design process, which abounds in many differences in comparison with usual design process.
The article deals with problems in designing and analyzing the membrane structure of a stadium roof. Attention is especially given to problems relating to the optimal design of the shape of the membrane (form finding) and the supporting cable system with respect to static behavior, functionality and architectural appearance. The work was carried out with respect to the companies Ing. Software Dlubal, s.r.o. and FEM consulting, s.r.o. intention to develop a new module of the RFEM program system capable of ascertaining the initial shape of a roof's membrane construction and also its analysis for both static and dynamic wind loads.
