Wind pressure measurements and scattering experiments were conducted using a full-scale severe storm generator (FSSG). First, scaled experiments were performed using a turbulent boundary layer wind tunnel to confirm the similarity of the wind pressure distributions on a full-scale model using the FSSG. Subsequently, J-shaped tiles that can measure surface wind pressures were fabricated using a 3D printer, revealing the wind pressure characteristics acting on roof tiles. Finally, scattering experiments were conducted using J-shaped and flat-shaped tiles for representative wind directions, and the results were presented.
