Single-layer spherical geodesic domes interacting with a network of inflatable beams

Abstract

In this paper we propose an example of a thin geodesic spherical dome composed by a lattice of inflatable interacting beams. The geometry of the lattice is determined by searching for the minimum variation of the characteristic dimensions of the elements that make up the dome (length of the bars and area of the panels). A first illustration of the mechanical response of the structure is given, with reference to the loads that usually are assumed to act on this type of shell.
