Abstract: The paper presents a numerical study of the effect of wind flow on a building rectangular in plan with an arch covering, taking into account the geometric parameters required for frameless metal arched structures. Computings are performed by use of the SolidWorks software package. The building under study is placed in the computational domain, which corresponds to a virtual wind tunnel. The Reynolds-averaged Navier-Stokes equations (Shear-Stress Transport turbulence model) form the theoretical and methodological background of the study.The paper elaborates the aerodynamic coefficients on the surface of the arch covering of a building and structure, taking into account changes in its height and geometric parameters of the coating, including establishing their main patterns of change. By means of experimental and static modeling, regression models for predicting aerodynamic coefficients are determined for given basic parameters, such as the arched boom (f) and the ratio of the height of the building to the span (h/L).
Keywords: arch covering, aerodynamic coefficient, numerical study, regression model.
