The spire shell of Sydney Opera House is covered with white glazed porcelain. In the sun, they are both like erect shells and like two huge white sailboats flying on the blue sea, so they are called "Sailboat Roof Theater".
The shell-shaped pointed roof consists of 265,438+094 arc-shaped concrete precast blocks each weighing 65,438+05.3 tons, which are tensioned by steel cables and cover 6,543,800 white or cream tiles. According to the designer in his later years, his creativity actually came from oranges.
Building structure:
The appearance of Sydney Opera House is like a white sail about to sail out to sea. It consists of 10 seashells, echoing the surrounding scenery, with the highest one as high as 67 meters. The appearance of Sydney Opera House is three groups of huge shells, which stand on the cast-in-place reinforced concrete structure base with a length of 186 meters from north to south and a width of 97 meters from east to west.
The first group of shells is on the west side of the lot. Four pairs of shells are arranged in a string, three pairs face north and one pair faces south. There is a big concert hall inside. The second group is on the east side of the lot, roughly parallel to the first group, with the same form but slightly smaller scale, and the opera house is inside. The third group is the smallest group in their southwest, which consists of two pairs of shells and has a restaurant inside.
