| Abstract |
The construction of another tall building in the close vicinity of existing building may lead to a modification in its response. Therefore, the wind loads on buildings in realistic environments may be considerably different from these measured on isolated buildings. Neighboring buildings may either decrease or increase the flow-induced forces on a structure, depending mainly on the geometry and arrangement of these buildings, their orientation with respect to the direction of flow and upstream terrain conditions. The main aim of paper was to investigate the between two prismatic-building models in two types of boundary layer flows representing suburban(α=0.15, BL1) and urban(α=0.30, BL2). A wind tunnel test was performed to determine how the wind loads on a rectangular structure are affected by the presence of prismatic-building structure upstream in the wind flow. This paper deals with mean and fluctuating as well as their spectra on a building due to an adjacent building of side ratio 1 for wind direction from 0 to 45 degree, every 15 degree and separation distance between two models. Interference effects were presented in the form of interference factors. And experiments were compared to these measured on isolated building. |
