TemporActive Pavillion: first loop of design and prototyping of an ultra-lightweight temporary architecture

The paper presents the project development of an ultra-lightweight temporary structure consisting of bending active GFRP arches, a restraining system made of stainless steel cables, and a translucent membrane envelope, with particular focus on the prototyping phase leading to the first construction of the pavilion. A multi-disciplinary team has collaborated to the realization of the first full-scale prototype, built with the aim of deepening a wide range of aspects related both to the optimization of the innovative mix of structural components and to the understanding of the installation constraints, typical of temporary architecture. The paper concludes by showing the results derived from the study and the lesson learned from the first prototype and foreshadowing further studies of the interface between structure and coating, also in relation to the different cycles of use and life-span of the pavilion.
