Sydney Opera House holds a special place in modern architecture. The Sydney
Opera House is not just another famous structure, but a building that is
a masterpiece of geometry, technology and architectural design. It was
built as a "signature building" and a symbol of the city. Functional and
powerful geometric forms combine to shape this building into one of the
most famous pieces of architecture in the world.
The geometry of the
shells define the Sydney Opera House. The shells were all taken from the
same sphere. Each shell was made up of series of ribs formed by parallel
lines. The shells intersect to create a look of sails. Engineers
could not calculate the precise geometry for the shell until the forces
and bending moments were known. These could not be calculated until the
exact geometric form was established. Engineers work on computers for almost
a year to develop the form of the shells. The Sydney Opera House was one
of the first buildings in the world to use computers in its design process.
Within the shells
you can what appear to be acute angles and obtuse angles.
Although formed from a sphere the shells seem to have the shape of an isosceles
triangle. There are panels in the building made up of ceramic tiles. These
tiles form tessellations that make repeated diamond patterns. The shells
and the panels are supported by a huge rectangular base.
