The aim of this diploma thesis is to show the possible range of shell shapes, which are applicable to be built using the -pneumatic wedge method-. Additionally the potential of the method will be clarified. Firstly a short historical summary of concrete, respectively reinforced concrete together with the evolution of shell constructions, is given. To amplify on this, it is followed by descriptions of existing representative shell structures of the early 20th century until today. Therein the development and functioning principles of the -pneumatic wedge method- are explained. The analysis of different geometries shows their suitability concerning the method and demonstrates the breadth of possible shapes that could be built by using this technique. Furthermore a particular form was chosen and tested on a scale of 1:5 and is currently being prepared for an actual size attempt. This wide range of possible forms and form variations demonstrates the potential of the method. In addition, there are various possible fields of application for this technology which is illustrated by Visualisations.
