Aerodynamic interference effects of a proposed taller high-rise building on wind pressures on existing tall buildings

When a large super high-rise building taller than the surrounding tall buildings is built in a dense urban area, the aerodynamic interference effects of the surrounding buildings on the proposed building attract much attention, while the interference effects of the taller high-rise building on the nearby existing buildings are often ignored. Based on a series of wind tunnel tests, the interference effects of a proposed taller high-rise building, an adjacent equal-height partner building, and relatively short background buildings on the target building's local wind pressures are analysed in this paper. Two-dimensional numerical simulation are carried out to further understand the interference mechanism in some cases. The test results show that the influence of a nearby proposed taller high-rise building may lead to wind-induced damage on the interfered shorter buildings' envelopes. The envelope structures of other surrounding buildings facing the side of the proposed building need to be given more attention.
