This thesis is part of a bigger research project which is being carried out at the Institute for Structural Engineering of the Vienna University of Technology, under the management and supervision of o.Univ.-Prof. Dr.-Ing. Johann Kollegger. The main aim of this work is the development of new construction techniques for shells which involve a simplification of the constructive procedures and a decrease of the economic costs. The basis of this work is the creation and the analysis of a semispherical dome by joining independent flat elements with a pre-stressed cable system. The chosen material for this first model is wood, but afterwards, the same technique is expected to be used for concrete and ice shells taking into account the obtained results.
In the first chapter of this project, of more descriptive nature, the definition of these kind of structures is studied, expounding the different existing kinds, as well as its functional characteristics and its analysis methods. Later an overview about dome history is shown using examples of the more outstanding constructions.
The second chapter constitutes the experimental part of the study. This section includes all the aspects related to the definition, design, construction and tests of the built model. Conclusions and improvement proposals are obtained from this first structure.
Computer models and analytical problems are developed in order to verify the validity of the obtained results and to study the feasibility of this new technique. Subsequently the results are compared and conclusions are made.
