Wind-tunnel tests on scale models predict that the twisting shape will reduce the lateral forces by 24 percent-and that will be critical when the next typhoon hits Shanghai. The twirling design slows wind currents as they circle the building, disrupting the vortex shedding that can cause a skyscraper to shake violently in the wind (the same way a blade of grass vibrates when you hold it between your fingers and blow). The tower, which from above looks like a guitar pick, twists approximately one degree per floor as it rises. Then they poured 2.15 million cubic feet of reinforced concrete to create an 20-foot-thick foundation mat.

Every 14 floors, two-story belt trusses hug the building’s perimeter each marks the start of a new zone. The columns buttress the building against lateral forces. A ring of steel “super-columns” surround the core, connected to it by steel outriggers. ![]() The first is a 90-by-90-foot concrete-and-steel core, which provides vertical strength. ![]() The building relies on three interlocking systems to remain upright. ![]()
