The wind pressure distributions on structures are one of the important parameters in terms of interaction wind load with structure. Some wind effects, especially interference effects, are still subject of the research and experimental measurements. EN 1991-1-4 standard can give only the wind external coefficients for alone cylinder. The wind flow around inline standing cylinders with buildings near to them is based on distances between them and local wind velocities. This paper deals with interference effects of wind flow around the group of circular cylindrical structures next to a building. In this research a CFD numerical analysis was carried out to investigate the interference effects in turbulent wind flow. Results of wind pressure distribution around cylinders were compared between CFD numerical analysis and EN 1991-1-4 standard.
