Investigation of the External Pressure Coefficients on the Facade of the Triangular High-Rise Structure with Curved Corners

The paper deals with the analysis of external pressure coefficients on the facade of high-rise building structure. The structure has shape of a triangle with curved corners. Analysis was performed mainly as an experimental study carried out in boundary layer wind tunnel. Second approach was performed by numerical simulation of wind flow using computational fluid dynamics (CFD) software module ANSYS CFX based on the Finite Volume Method. One of these experimental results was compared with numerical simulation to prove precision and verification of computational analysis. Both methods used scaled model of the structure. For the wind tunnel experiment, 31 points of interests around an object were monitored in steady wind flow and from those points, results of external pressure coefficients from 6 directions of wind flow were obtained.
