Abstract

Methods for determination of the wind pressure distribution on the facade of the atypically shaped high-rise building structure will be shown. The standard Eurocode 1 [1] does not mention recommendations for calculation of wind pressure distribution on the facade for the most cases of buildings having an irregular cross-section. Analysed object has a shape of the equilateral triangle. For the determination of the pressure distribution two methods were used. Experimental analysis was carried out in the boundary layer wind tunnel and second approach was performed by numerical simulation of wind flow using computational fluid dynamics (CFD) software based on the finite volume method. Both methods used scaled model of the structure. For the wind tunnel experiment, 16 points of interests around an object were monitored in steady wind flow and from those points, results of external pressure coefficients from 2 directions of wind flow were obtained. In conclusion comparison of results of both methods will be shown.
