Exoskeleton Buildings
Exoskeleton buildings are a game-changer in the world of architecture. They allow for flexible floor plans free of columns, making them ideal for residential high-rises.
The 20-story residential high-rise at 170 Amsterdam Avenue on the Upper West Side of Manhattan features a concrete exoskeleton with a diagrid design. This design was made possible by newly available modeling technology.
A specialized concrete mix was used for the exterior structure, which was made to look like limestone. Fiberglass was also used on the exterior to achieve a specific aesthetic.
DeSimone, the structural engineering firm behind 170 Amsterdam Avenue, received a Diamond Award for Structural Systems from the American Council of Engineering Companies in 2016. This award recognizes innovative structural engineering solutions.
One Thousand Museum in Miami, Florida, is another notable example of an exoskeleton building. It features a curved "root" exoskeleton structure designed by Zaha Hadid.
Placing the building's support systems on the exterior allows for increased space inside and reduces the amount of materials used. This approach was also used in The Grove at Grand Bay project.
The exoskeleton structure at One Thousand Museum was originally purely cosmetic, but DeSimone was able to integrate the design into the structural engineering. This created the exterior support structure out of hollow, precast, concrete panels.
