The Tianjin CTF Finance Centre is a 530m super-tall building nearing completion in the People's Republic of China. For a building of this height, wind forces and associated wind-induced motion in the upper levels can become dominant factors in the structural design of its foundations and lateral-stability system.
This article describes how an initial aerodynamic shape-optimisation workshop allowed the design team to develop a finely tuned architectural form capable of minimising the detrimental effects of vortex shedding.
