There is another tensegrity structure based construction in Buenos Aires, Argentina. The La Plata City Stadium was built in the late 1990s. It’s the first of its kind. The construction of the roof of the recent stadium in La Plata combines with two concepts: Architect Roberto Ferreira’s award winning entry into the competitions and the structure of Tenstar Dome that Weidlinger Associates built for Georgia Dome.
The La Plata project posed some particular technological problems similar to the Georgia Dome. Two overlapping circles representing the two soccer clubs that share the facility derive the geometry of this arrangement. There are two overlapping circles that form the unusual geometry of the structure, reflecting the two soccer clubs which share the facility.
The main building was completed in the early 2000s on budget but due to the Argentinian economic crisis, the construction of the iconic roof was suspended. Construction was restarted in 2009, with the resurgence and selection of Argentina as hosts of the 2011 Copa América. The finished configuration represents the first modification of a tensile roof structure and is the very first covered stage of Polytetrafluoroethylene (PTFE) in South America. The reliability of the La Plata stadium cable structure does not depend on its PTFE panels, unlike other tensile roof structures.
The tensegrity architecture of La Plata resists to global stress distortion. The deck roofs are also exceptionally rigid, similarly to stiffening a drum skin. The architecture is more similar to a cable dome structure and is thus more similar to a traditional roof structure, according to the proprietary Tensegrity roof concept. Snelson published the first studies on the creation of tensegrity grids, but its use was minimal. The creation of double-layer Tensegrity grids and foldable Tensegrity systems has been the subject of attention over the last few years. In the area of walls, roofs and covered buildings, this sort of grid is most feasible.
