“…In fact, although there are some quantitative inconsistencies in the results between 2D and 3D LES, 2D LES with a fine grid resolution is still a sufficient and desirable way to show the trends of flow patterns around bluff bodies. Recently, Lo et al successfully used a 2D LES model to study the interference effect of a vibrating building on vortex shedding and pointed out that it is also an intuitive way to understand the interference mechanism between 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

“…The dynamic torsional responses were also increased due to the wake of an upstream interfering building. Recently, Lo, Kim, & Li (2016) used aeroelastic testing to identify another critical location of ( , ) = (−2 , 0) for interference between two identical high-rise buildings, where the building has very strong crosswind vibration. All these studies only focused on the generic building shapes like square prism or rectangular prism buildings.…”

Summary Opening ventilating holes on a supertall building is an effective way to reduce its wind‐induced structural response and enhance its wind‐resistant performance. However, its interference effect on the neighboring supertall buildings has seldom been studied yet. Taking two actual neighboring buildings, the Guangdong International Financial Center (IFC) and the Guangzhou Chow Tai Fook Finance Centre (CTF) as examples, this study carried out high‐frequency force balance wind tunnel tests to investigate the interference effect of the IFC's ventilating openings on the wind‐induced response of CTF. Results show that when CTF is located in the downstream area of IFC, the ventilating openings on IFC make the high‐energy frequency band of the power spectral density (PSD) of CTF's crosswind aerodynamic load offset obviously towards the lower frequency interval. Consequently, the wind‐induced response of CTF can be significantly magnified or minified depending on the reduced structural natural frequencies. Since the reduced natural frequency for the structural base bending moment computation is usually smaller than that for the acceleration response computation, ventilation openings on IFC can be advantageous to the crosswind base bending moment response relevant to structural safety design, and disadvantageous to the acceleration response relevant to occupant comfort assessment.
