Abstract

The existing methods for determining the wind load coefficients are analyzed in order to identify the features of the influence of the type of distribution on the forces from the impact of the wind on the structures of buildings and structures of a prismatic type with different proportions of the frontal surface. Reinforced concrete buildings with the first frequency of natural vibrations greater than the limit value were considered. The study was carried out on the basis of the study and analysis of the main provisions of regulatory documents regulating design and development activities in the Russian Federation, as well as relevant works of domestic and foreign scientists relevant to research in this area. The research method is structural-analytical analysis using the correlation dependences of the studied factors. Analytical dependences are given to determine the forces from the wind with various methods of assigning the coefficient of the pulsating wind load along the height of the building, taking into account the shape and proportions of the wind surface, as well as their graphical interpretation. The work is based on the provisions of domestic building codes and regulations and relevant information contained in other domestic and foreign sources and standards. It has been established that in buildings of a prismatic shape there are separate sections where the forces from the components of the wind load significantly depend not only on the proportions of the frontal surfaces, but also on the methods used to establish the distribution law of the coefficients. The conducted research indicates the ambiguity of the results obtained, allowing the possibility of exceeding or underloading structures or individual elements. The results of the work make it possible to correct calculations for establishing the values of wind loads for the considered types of buildings and height ranges and to predict for other objects with different parameters.
