At 632 meters and 128 stories, the mixed-use Shanghai Tower will be the tallest building in China once it is completed in 2014.
Three design concepts were developed in response to Shanghai’s extreme wind conditions: an asymmetrical facade, a tapering shape, and consistently rounded corners.
The asymmetry and taper of the building work together to reduce wind loads on the building by 24 percent, providing a savings overall in both building materials and construction costs. The tower incorporates 4 pairs of super columns rather than a ring of columns around the circumference.
Wind tunnel testing on a 1:85-scale model focused on validating the optimal tower shape and showed that reducing wind load allows for a lighter and more efficient structure. Using a computational fluid dynamics model, the team simulated internal temperature and air-flow distribution.
Optimized for high performance and sustainability, the tower is China’s tallest building and can be viewed as a symbol of a future filled with opportunity.
