Museum of Contemporary Art (Niteroi, Rio de Janeiro, Brazil)

One of the most amazing building.

 Built in 1996 the Niteroi, Museum of Contemporary Art in Brazil is anothe strange and beautiful building; the Musium in Niteroi was designed by architect Oscar Niemeyer with help from structural   engineer Bruno Contarini.

The Museum in Rio de Janeiro only allows for a about 60 people in the Hall of Expositions, its impressive structure is likened to a UFO as it has a disc shape set on the cliffside reminiscent of a Science Fiction UFO landing and opening up.

Niemeyer designed a radial structure sixteen feet high, with a deck of fifty meters in diameter and almost 2000 square meters which is based on a single central support cylinder 9 feet in diameter anchored in a giant shoe two meters . This complex structure that appears to float in the air was designed to withstand a weight equivalent to 400 kg / m² and winds up to 200 km / hour.

The large central hall with 462m2, completely free of columns and contoured at the top by a wide space for smaller samples, named as mezzanine, has promoted the implementation of large tables and radial girders under the roof of the Museum. These beams are supported by six pillars of 50 cm in diameter.

Pictures of beams and columns are thus a kind of table that is in turn supported on the structure of the first floor. The weight of the superstructure, transmitted by the columns of the above "table" on the first floor is supported by a set of radial beams prestressed concrete made also on the supporting pillar. These beams are projected on balance about 10 meters.
