The article considers the modeling of wind impact on the objects of parametric architecture. To determine the optimal shape of the surface, the evolution of the analytical surface shaping, formed by congruent curves in parallel planes, obtained by the rotation of the reulault triangle with a plane perpendicular to the axis of rotation, is studied. Based on the results of a numerical experiment using the finite element method, the rational analytical surface of the object of parametric architecture, resistant to wind, is determined. The dynamic characteristics of the object of parametric architecture are obtained. Recommendations are given to clarify the methods of determining the wind load for buildings and structures of complex geometric shape.
