Wind response of interference effect on tall building

The construction of a tall building in close proximity to an existing building may affect the response to wind load of the latter. Therefore, wind loads on buildings in realistic environments may differ considerably from those on isolated buildings. Neighboring buildings may alter the flow-induced forces on a structure and this is particularly dependent on the geometry and layout of the buildings and their orientation with respect to the direction of flow and upstream terrain conditions. The main aim of this paper is to investigate the differences between two prismatic building models for two types of boundary layer (BL) flow: suburban (BL1) and urban (BL2). To investigate the interference effects on dynamic responses of tall buildings, a high-frequency force-balance test was conducted.
