Abstract

Many high-rise buildings have been made due to the improvement of earthquake resistance and wind resistance performance of buildings. It is important to consider the safety and stability of such buildings. Especially in urban areas buildings are built in various sizes.In this research, when two prismatic structures were arranged in parallel, three dimensional numerical calculation was done with the aim of capturing the aerodynamic characteristics of those structures. For numerical results, we show the fluid force acting on a structure and the flow behavior around a square prism when changing the interval between two prisms
