The Sears Tower, now officially known as the Willis Tower, stands as one of the most recognizable landmarks in the world, boasting a rich history and architectural marvel. Located in the heart of Chicago, Illinois, this skyscraper has been a symbol of American ingenuity and engineering prowess since its completion in 1974. Among the many fascinations surrounding this tower, one question often arises: What is on top of the Sears Tower? This article aims to delve into the intricacies and attractions found at the pinnacle of this iconic structure, exploring its design, features, and the breathtaking views it offers.
Introduction to the Sears Tower
The Sears Tower, designed by architects Bruce Graham and Fazlur Rahman Khan of Skidmore, Owings & Merrill, was the world’s tallest building upon its completion, standing at a height of 1,450 feet (442 meters) with 110 stories. It held this title for over 20 years, until the completion of the Petronas Twin Towers in Kuala Lumpur, Malaysia, in 1998. The building was commissioned by Sears, Roebuck and Co. and served as the company’s headquarters until 1994. In 2009, the London-based insurance broker Willis Group Holdings acquired the naming rights, leading to the tower’s official renaming to the Willis Tower.
Design and Structural Innovations
One of the most striking aspects of the Sears Tower is its innovative design, which was groundbreaking for its time. The tower features a bundled tube structure, where nine individual tubes are bundled together to form a single, strong unit. This design not only provides immense strength but also allows for more interior space by reducing the number of internal columns needed. The exterior of the building is covered in black anodized aluminum and bronze-tinted glare-reducing glass, giving it a distinctive dark appearance that has become synonymous with Chicago’s skyline.
Engineering Marvels
The engineering behind the Sears Tower is a testament to human innovation. The building is designed to sway slightly in the wind, a feature that helps it withstand strong gusts and reduce the stress on the structure. Furthermore, the tower’s foundation is anchored to a deep layer of limestone, providing a solid base that supports the entire weight of the skyscraper. These engineering feats contribute to the tower’s ability to support both the weight of the building itself and the forces exerted by nature.
