The Sears Tower

When the Sears Tower was constructed in 1974, it was labelled the tallest building in the world. This prestigious title remained in Chicago for no less than 23 years, until the Petronas twin towers in Kuala Lampur were finished in 1997.

Sears Tower was designed in the late sixties by Skidmore, Owings, and Merrill for Sears Roebuck. The building consists of nine framed tubes, which are actually nine skyscrapers incorporated into one structure. Originally, the plan included fifteen tubes, but later, only nine tubes were used for the final project. The building is designed in such a way that not all the tubes have the same height. The result is a most interesting tower with a different aspect from various angles. Its curious design is also considered one of the most efficient structures in the world made to withstand the city's legendary winds. Although are no longer the "world's tallest building", the 110-story Sears tower is still an example of the revolutionary bundled-tube structural design. Steel frames with bronze-tinted glass curtain walls were used to cover the building.
