SOM’s wind-battling supertall tower breaks ground

Ground has broken on SOM’s latest supertall building, the 530m-tall CTF Tianjin Tower in Tianjin, China, which is designed to reduce wind load.

The 96-storey tower contains offices, 300 service apartments and a 350-room, five-star hotel beneath its boldly arched top.

Its gently curving glass skin conceals eight sloping columns that increase the structure’s stiffness in response to seismic concerns.

SOM structural and civil engineering partner William Baker, commented: “The single most important structural parameter of a tall building is the architecture.

“The CTF Tianjin Tower will be significantly quieter, with less movement than other tall buildings. We tested 18 schemes in the wind tunnel before finalising the design.”

Strategically placed, multi-storey wind vents, combined with the aerodynamic shape of the tower, are said to dramatically reduce wind forces.

The 390,000m2 project has been designed to LEED gold standards.
