Largest structure in the world supported by glass
Have you seen this? The winner of the Institute of Structural Engineers Artistry award – the Steve Jobs Theater Pavilion in California. The 47m carbon fibre roof is the largest of its kind, comprised of 44 radial panels, which were assembled on site before being raised into position in one lift. This 80 tonne roof is supported by a 7m high glass cylinder, made up of glass panels, each consisting of four layers of 12mm thick plies, which hold up the roof without any additional support. It is the largest structure in the world solely supported by glass.
The structural systems were designed so that the conduits, sprinkler pipes, data, audio and security systems needed in the roof could be accommodated in the 30mm joints between the glass panels. As Cupertino is in a highly seismic zone, several strategies have been employed to protect the structure against seismic activity. More here
