Pressure Field Correlation for Buildings with Hyperbolic Paraboloid Roofs: Results of Wind-Tunnel Tests
The aerodynamics of roofs with a hyperbolic paraboloid shape is almost neglected by codes. However, this shape is commonly used to cover large spans through tensile structures or light shells. Due to their lightness and size, these structures are very sensitive to wind, that may produce very complex pressure distributions. The correlation structure of wind-induced pressure fields plays therefore a relevant role, because it affects the resultant forces to be included in the design of structural elements, at different scales, and this aspect has not yet been fully explored in the scientific literature for this shape. Based on experimental tests performed in the CRIACIV boundary-layer wind-tunnel in Prato (Italy) on in-scale models, this paper investigates, as a part of a wider research, the correlation structure of the pressure field on buildings with a hyperbolic paraboloid roof. Namely, the loss of correlation of the experimental pressure distribution on a sample model is described by evaluating the effective pressure coefficients on regions of increasing size around significant points of the roof, for different angles of incidence of the wind.
