Super-tall buildings are subject to considerable wind loading and wind-induced effects as height increases, which has become one of main factors to influence the safety, the occupants’ comfort and the expenditure of structures, so it is of particular importance to control the wind loading and effects of super-tall buildings. In general, methods to control wind loading and effects of tall buildings are the application of aerodynamic measures and the installation of supplementary damping systems. This paper presents an overview of past/recent work on aerodynamic measures for suppression of loading and effects of tall buildings in the across-wind, along-wind and torsional directions, as well as local pressure, and then briefly introduces supplementary damping systems in controlling wind-induced vibration. Applications of aerodynamic measures and supplementary damping systems to control wind loading and effects of typical super-tall buildings are exemplified. Finally, issues worthy of attention are proposed for future researches.
