Internal forces in the frame of building of prismatic form under different distribution of wind pressure

Abstract

The features of the effect of wind on a prismatic-type building with different methods of determining the coefficient of wind pressure along the height are considered. The study was carried out on the basis of studying the main provisions of regulatory documents governing design and development activities in the Russian Federation, as well as current publications of domestic and foreign scientists, corresponding to research in this area. The research method is structural and analytical analysis using the correlation dependences of the factors under study. Analytical dependencies for determining the wind forces for various methods of assigning the wind load coefficient along the height of the building and their graphic interpretation are given. The work is based on the provisions of domestic building codes and relevant information contained in other domestic and foreign sources. For prismatic buildings with a height of up to 80 meters, there are areas where the forces from the main wind load significantly depend on the method of its determination. The conducted research indicates the ambiguity used in the practice of designing the parameters of the wind load, allowing the possibility of excess or underloading of structures or individual elements.
