Over the last few years different methods for building shells by using a combination of pneumatic formwork and post-tensioning technologies have been investigated at Vienna University of Technology. The idea behind all these construction methods is to build ice shells with double curvature originating from an initial plane plate. The various construction methods will be presented and the experiments on spherical shells with base diameters of approximately 10m will be described.
