Annotation: The article analyzes the classification of civil buildings by the form of their grouping in urban development, identifies the main forms of development. The systematization of the ratio of distances between the studied model and the obstacle models, the building configuration, and a program for conducting large-scale experiments in a wind tunnel are presented. The results of experimental studies in a wind tunnel are also presented, and the distribution of aerodynamic pressure coefficients on models of a mass-construction building is determined. The patterns between the distribution of wind pressure from the geometric parameters of the building and the building configuration are revealed. A mathematical model of the flow around prismatic cylinders simulating buildings based on the method of least squares and point calculus has been developed. On the basis of the developed mathematical model, the dependences of the distribution of pressure coefficients (Cp) on the building surface in buildings of various configurations are constructed. It has been determined that the distribution of wind pressure coefficients (Cp) on the windward and windward sides of a building Cн and Сп, located in a building, differs from the pressure on the windward Сн = +0,8 and windward Сн = –0,6 sides of a detached building, taken as standard.
Keywords: buildings of mass construction, buildings of various configurations, aerodynamic coefficient, wind load, wind tunnel.
