Wind Response of Interference Effect with Tall Buildings

Abstract

The construction of a tall building in the close vicinity of existing buildings, may lead to a modification in its wind response. Therefore, the wind loads on buildings in realistic environments may be considerably different from those 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 and their orientation with respect to the direction of flow and upstream terrain conditions. This paper deals with mean and fluctuating models, as well as their spectra on a building, due to an adjacent building of side ratio 1 for wind direction from 0 to 45 degrees and the separation distance between two models. Interference effects were presented in the form of interference factors, findings were compared to analogous measurements of an isolated building.
