The Sears Tower currently known as Willis Tower

Following written copy from the Chicago Architecture Foundation.
Architects have always been tasked with designing tall buildings to resist wind loads. But as buildings continued to grow taller and taller, new solutions were required. When this 110-story tower was designed, architect Bruce Graham and structural engineer Fazlur Khan of Skidmore, Owings & Merrill (SOM) utilized the bundled tube system to address structural problems never before seen at this scale. Their use of the innovative system ushered in a whole new era of skyscrapers.

The tower is comprised of a cluster of nine tubes connected together to act as a single unit. The tubes support one another, strengthening the structure as a whole. Meanwhile, the variations in tube height disrupt the force of the wind.

Marina City

Architect Bertrand Goldberg. Copy from Chicago Architecture Foundation: Forward-thinking architect Bertrand Goldberg was a student of Ludwig Mies van der Rohe, and the influence of Mies’ Modernist principles can be seen in his work. But his own ideas of modular, prefabricated, curved forms are also highlighted in the design of Marina City. Goldberg believed that since no right angles exist in nature, none should exist in architecture. That belief is clearly at work in the 65-story residential towers’ design.

Goldberg compared the bays on Marina Towers to the petals of a sunflower. They radiate from the building’s strong central core and provide stunning balcony views for each wedge-shaped residential unit. The curvilinear reinforced concrete forms became a trademark of Goldberg’s style.

The tornado exhibit at the Museum of Science and Industry in Hyde Park. World class place. I recommend it for everyone. A million ways for kids and adults to interact.
