Wind tunnel investigation of the aerodynamic performance of temporary pyramid shelters in emergency conditions

With the growing frequency of natural disasters, the need for sustainable emergency shelters has become increasingly urgent. This study evaluates the aerodynamic performance of pyramid-shaped shelters through wind tunnel testing of eight scaled models with hexagonal and octagonal bases at angles ranging from 0° to 180°. Surface pressure coefficients were measured to assess wind effects. While hexagonal models showed higher pressure peaks, octagonal models offered more stable aerodynamic behavior due to more uniform wind load distribution. Pressure fluctuations were most significant near the edges, with relative stability observed between 120° and 140°. These findings suggest that increasing the number of base sides improves wind resistance, offering insights for optimizing temporary shelter designs in disaster-prone regions.
