This paper presents the experimental determination of wind loadsWind loads acting on a large spatial lattice structure covering the new passenger Terminal at Rabat-Salé Airport, Morocco. Due to the unique shape of the structure and the lack of suitable literature references for determining wind-induced pressure coefficientsPressure coefficients, a wind tunnelWind tunnel campaign was necessary. The collected data were processed through a frequency-domain dynamic approach to determine the internal forcesInternal forces in the roof members and support reactions. The structure resulted to be very sensitive to wind dynamic excitation, especially in the external cantilever parts, with a predominance of resonant to quasi-static contributions. Given the geometric and dynamic peculiarity of the structure, wake signature also plays a significant role in the response.

Due to the unique shape of the structure and the lack of suitable literature references for determining wind-induced pressure coefficientsPressure coefficients, a wind tunnelWind tunnel campaign was necessary. The collected data were processed through a frequency-domain dynamic approach to determine the internal forcesInternal forces in the roof members and support reactions. The structure resulted to be very sensitive to wind dynamic excitation, especially in the external cantilever parts, with a predominance of resonant to quasi-static contributions.
