Wind tunnel tests of the effects of aerodynamic interference on a stadium roof

Abstrakt

This paper summarizes results of wind tunnel tests of a non-standard stadium roof. Aerodynamic laboratory studies were accomplished in a boundary layer wind tunnel. The main objective of the research was to determine the distribution of the mean wind net pressure coefficient over the stadium roof surfaces as affected by the aerodynamic interference between the stadium structure and a large oval sports event hall, located nearby. Interference coefficients of wind pressure and global wind forces acting upon the surfaces of the stadium roof were calculated. The aerodynamic studies showed a significant influence of the oval Atlas Arena sports-event hall on the wind load subjected to the stadium structure.
