| Title of the article | Numerical calculation of the maximum peak wind load for a rectangular building |
| Abstract. | Problem statement. It is known that wind suction occurs at the corners of a rectangular building. According to regulatory standards, the negative pressure coefficient for all building profiles is recommended to be equal to 2.2. The purpose of this article is to determine the maximum wind load on the angular sections of the horizontal section of a high-rise building by numerical calculations. The tasks of the study include conducting two-dimensional numerical calculations of the flow around a square and rectangular prism, conducting a numerical calculation using a rectangular high-rise building as an example, comparing integral and distributed aerodynamic characteristics with available experimental data, and comparing numerical results with regulatory data. Results. Based on the numerical solution in the ANSYS Fluent program of a two-dimensional problem of flow around a separate square and rectangular prism with an aspect ratio of 0.6, the coefficients of drag, lateral force, distribution of the pressure coefficient along the contour of these profiles were obtained. Integral and distributed characteristics were also obtained for a rectangular profile of a high-rise building with an aspect ratio close to 0.6. According to the results of calculations, a significant wind suction is noted on the angular sections of rectangular profiles. The negative pressure coefficient on the edges of a rectangular prism and a rectangular building is approximately 30% greater than that of a square prism. There is a good agreement between the peak value of the negative pressure coefficient for a square prism and the standard value. Conclusions. The significance of the results obtained for the construction industry lies in the possibility of using the pressure coefficient on the corner sections of rectangular buildings with an aspect ratio close to 0.6 when calculating the peak wind load for fencing elements and their fastening points. |
