Abstract

Transformations of tensioned membrane elements M. Mollaert, S. Hebbelinck Faculty of Applied Sciences, Department of Architecture, Vrije Universiteit Brussel, Belgium Abstract The paper shows some existing retractable membrane structures. In most cases the opening of the roof means that the membrane hangs freely and that all pre- tension is released. It is the aim to analyse the possibility to open a roof by a combination of motion and transformation: membrane units are tensioned into (slightly) different forms. First a structure, composed of identical wave formed membrane units, identical bar elements and cables, is proposed. The membrane elements are placed in a rectangular pattern like roofing tiles. With a sliding motion units can move one under the other. The form of the units remains almost the same. Next a scissors system with wave formed membrane units is considered. The scissors are folded to open the roof. The membrane units have to change t
