Aerodynamic force coefficients for structural members of automated rack supported warehouses

A wind tunnel experimental campaign was carried out on steel structural members employed for automated rack supported warehouses. Two-dimensional static force measurements were performed on steel profiles for vertical (upright) and horizontal (beam) elements, to determine aerodynamic forces acting on the single tested element for different angle of attack values. Results were compared one to each other and to general indications provided by standards and codes and they were discussed. Similarities were found between all tested elements in terms of aerodynamic coefficients against sectional side ratio. This was also confirmed by a comparison of experimental results to standard and code indications.
