This article presents results of model tests of pressure distributions over interior and exterior surfaces of a utility building model carried out in an boundary layer wind tunnel. The tests were carried out taking into consideration different variants of solidity ratio coefficient values of the structure’s side walls. The main aim of the analyses was to determine the influence of the solidity ratio coefficient values of the side walls on the wind pressure distribution over the interior and exterior surfaces of the object. Four configuration variants of the side walls were taken into account for two directions of air flow – perpendicular to the gable wall and perpendicular to the side wall. The achieved results were analysed.

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.

This paper summarizes results of wind tunnel tests of a high-rise building placed in Warsaw city centre. 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 pressure coefficient over the building’s external surfaces as affected by the aerodynamic interference between the structure and its immediate city surroundings. Interference coefficients of wind pressure and global wind forces acting upon the surfaces of the building walls and roof were calculated. The aerodynamic studies showed a significant influence of objects located nearby on the wind load that the high-rise building structure surfaces are subjected to.

Wind tunnel tests of acoustic panels

PL
The paper summarizes the wind tunnel tests of original acoustic panels located on the block buildings roofs near edge of building roof and walls. Performed investigations had two main goals: 1. Verification of resistance of the panels at their connecting members at high air flow velocities; 2. Determination the set of aerodynamic force coefficients, obtained from measured wind pressure distribution on the façade panel surfaces in two opposite wind directions, was the main aim of the work.
