Reinventing the Skyscraper: Tianjin CTF Finance Center
A dramatic, undulating profile distinguishes this 530-meter-tall tower as a new landmark in the growing Tianjin Economic-Technological Development Area (TEDA). The tower’s design is a synthesis of architectural, structural, and functional requirements. It contains high-end office spaces, apartments, and a five-star hotel, arranged to match the optimum spans for each of these uses—with longer lease spans for the office floors, and shorter spans to maximize views at the apartment and hotel levels. The gently curving glass skin conceals eight sloping columns that lie behind the primary bends of the elevation and increase the structure’s stiffness in response to seismic concerns. Wind loads were dramatically reduced by the aerodynamic shape and the porous crown. The 389,980-square-meter project has a striking silhouette, defined by a series of curves that converge at an open-lattice crown. A glass facade sheaths the sinuous form of the skyscraper, making a dramatic impression as it reflects the sky.
