Abstract:
In order to investigate the wind pressure variation patterns of complex-shaped large-span natatorium structure under wind load, a large-span natatorium structure in Xi'an was taken as the research object. By employing numerical simulation of wind load, the changes of average wind pressure coefficient on the roof surface of natatorium structure under different turbulence models and wind direction angles were studied. The influence of turbulence models and wind direction angles on the roof structure of natatorium was analyzed. Subsequently, the impact of different zoning buildings on the average wind pressure coefficient of natatorium structure was considered to derive the influencing patterns. The results show that different turbulence models have a negligible effect on the average wind pressure coefficient of natatorium roof. The average wind pressure coefficient on the roof surface of entire natatorium model exhibits a gentle variation gradient at wind direction angles of 90° and 270°, and maintaining a value close to -0.5. The average wind pressure coefficient shows a more pronounced variation gradient at other wind direction angles. The average wind pressure coefficient of the concave part of natatorium eaves is very small, and even positive wind pressure occurs, while the convex arc-shaped part has a larger negative wind pressure. When the incoming flow moves from low to high, the lower B and C zones ahead form a gentle slope structure with respect to A zone, effectively resisting some of the airflow and reducing the wind pressure in A zone, resulting in a relatively smooth gradient of the average wind pressure coefficient.
