PROJECT DESCRIPTION

Located in the Lujiazui Finance and Trade Zone, Shaghai Tower stands 632 meters tall, a supertall building for which the principle structural frame consists of concrete columns at the circumference, connected to the core by lattice steel outriggers at service floors for added stiffness.

One of the principle engineering features is the double-skin curtain wall where the inner skin envelops wraps around the cylindrical floor plates, while the outer skin twists 120° and tapers from bottom to top. The space between the skins acts as a thermal barrier, much like a thermos.

Judge's comment:

The structural design of this super high-rise tower uses multiple outriggers and circumferential frames throughout the height of the building, combined with reduced wind loads due to the irregular aerodynamic configuration of the fa├žade, and a magnetic vortex tuned mass damper.  The foundations in very soft silt, and construction of the deep basement, also provided considerable engineering challenges.
