Tianjin CTF Finance Centre is a supertall skyscraper in Tianjin, China. Construction started in 2013 and was completed in 2019. The tower is the second tallest building in Tianjin after Goldin Finance 117, eighth tallest completed building in the world, and the tallest building with less than 100 floors. It is located in the outer district of the Tianjin Economic-Technological Development Area.
The building commonly designed as the softly curving glass skin integrates eight sloping megacolumns that follow a lyrical line connecting the centers and corners of all four elevations. These curving megacolumns increase the structure’s response to seismic concerns and are integral to both the gravity and lateral systems. They are effective in increasing the stiffness of the building’s perimeter frame, consequently attracting a larger portion of the seismic forces in compliance with the Chinese code requirements.
The façade reinforces the curvature of the tower form and creates a shimmering texture over the building’s surface. The crystalline-like curtain wall stretches from the suspended glass canopies at each of the lobbies to the dematerialized, megacolumn-looped crown and presents a bold expression of a comprehensive, integrated design on the Tianjin skyline.
By stacking reducing floor plates, the tower tapers dramatically to minimize the surface area exposed to wind, sun, and moisture. The gently-undulating curves of the façade subtly denote the integration of the three distinct programs within a singular smooth object. Square in plan with rounded corners, the floor plate geometry enables unique interior fit-outs and customization options for occupants. Research by the architect has shown that lateral forces due to vortex shedding can be controlled by tapering the vertical profile of the tower and softening any sharp corners in plan. The building’s aerodynamic shape greatly reduces this vortex shedding by “confusing the wind” and disrupting the opportunity for any resonating wind forces and loads on the structure.
