Shanghai Tower

Highlights

• The tower features a twisting triangular form with a façade that curves 120 degrees from its base.
• Its structural system consists of a 90-by-90-foot concrete core connected to a system of outriggers and super columns supported on 1,079 concrete and steel bore piles driven deep into ground.
• The outrigger trusses and super columns derive stiffness from the concrete inner building, comprising an effective system for resisting wind and seismic loads for supertall buildings.
• We refined the tower’s form and reduced building wind loads by 24 percent, which resulted in a lighter structure and reduced material cost.
• A double-hung pendulum tuned mass damper reduces building movement caused by wind.
• The tower features a variety of sustainable technologies, including wind turbines and solar panels as renewable energy sources to achieve a low carbon footprint.
