Abstract
To improve safety and serviceability of super-tall buildings in strong winds, aerodynamic optimization of
building shapes is considered to be the most efficient approach. Aerodynamic optimization is aimed at
solving the problem from the source in contrast to structural optimization which is aimed at increasing
the structural resistance against winds. However, there are two challenges that usually limit the
applicability of aerodynamic optimization in design practice. One is a potential conflict between
optimization schemes and other design aspects, and another is a potential conflict between cost and
effectiveness. To minimize these conflicts, it is important to conduct aerodynamic studies in early design
stage to gain reasonable assessment on various optimization options. This paper summarizes the
aerodynamic approaches that have been used with success in building designs, and discusses the
principles and effectiveness of these approaches. To provide a guideline for preliminary design, this
paper proposes a practical approach to assess the effectiveness of tapering, twisting and stepping, the
three common schemes of aerodynamic optimization in super-tall building design.
