Willis Tower Size report

The Willis Tower is a skyscraper in Chicago, Illinois; its former name is the Sears Tower. Built-in 1974, Chicago's Willis Tower held the title of the world's tallest building from 1974 to 1998. It was surpassed by the Petronas Twin Towers in Kuala Lumpur.

The original owner, Sears-Roebuck, moved out in 1992, and the building has since been owned by a real estate investment group established in 2004. In 2009, it was officially renamed Willis Tower. With 110 floors, Willis Tower was once the tallest office building in the world. About 16,500 people come to work here every day.

The Willis Tower is 412 meters high above the ground. When the weather is clear, visitors can see the four neighboring US States from the tower's viewing platform. On the 103rd floor is a viewing platform for tourists to overlook the city. In this post, let's learn more about the Willis Tower's appearance and size.

Description of the Willis Tower Size

The Willis Tower was designed by architect Bruce Graham and structural engineer Fazlur Khan. Fazlur Khan proposed and put into practice the concept of beam tube structure system to solve the problem of the wind-resistant structure of high-rise buildings like The Willis Tower. All towers are the same width but at different heights.

The Willis Tower uses a steel-framed bundled-tube structural system with an exterior envelope of black aluminum and coated glass. The shape of the building is like a group of 9 square hollow tubes of different heights. The facade shapes vary in different directions. This beam tube structure system results from architectural design and structural innovation. Skydeck opened in 1974 and is the highest observation deck in the United States. With the renovation of Skydeck came The Ledge. The Ledge offers breathtaking views, with two glass cubes protruding 4.3 feet from the building's facade. The bottom of the glass viewing platform is also made of transparent glass.
