Skyscraper office building in Chicago.With 110 floors and a height of 1,450 ft (442 m), it became the world's tallest building at its completion in 1974. Its architect, Fazlur Khan (1928–1982), designed it as a bundled-tube (see skycraper) structure to resist lateral forces. It is modular in plan, with nine 75-ft-(23-m-) square, column-free units. The exterior is sheathed in black aluminum and bronze-tinted glass. Louvers clad the four floors devoted to the building's mechanical operations. It was the world's tallest building until 1996, when it was surpassed by the Petronas Twin Tower (1,483 ft [452 m]) in Kuala Lumpur, Malaysia.
