    The distinctive paper is devoted to the methodology of pedestrian comfort estimation in the nearby area of the object under construction. A verification example of the wind flow simulation around and through a porous object is considered in order to select correct permeability parameters of the computational model of green spaces. The methodology of pedestrian comfort estimation is tested on the example of a real residential complex in Moscow. The results of the numerical simulation of velocity fields are used to calculate the criteria for pedestrian comfort specified in MDS 20-1.2006. Numerical results are obtained and compared for two study cases -without and with green spaces (bushes),to assess their impact on pedestrian comfort and the possibility of its adjustment.Настоящая ΡΡ‚Π°Ρ‚ΡŒΡ посвящСна ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΈΠΊΠ΅ ΠΎΡ†Π΅Π½ΠΊΠΈ ΠΏΠ΅ΡˆΠ΅Ρ…ΠΎΠ΄Π½ΠΎΠΉ комфортности Π² Π±Π»ΠΈΠ·Π»Π΅ΠΆΠ°Ρ‰Π΅ΠΉ Ρ‚Π΅Ρ€Ρ€ΠΈΡ‚ΠΎΡ€ΠΈΠΈ строящСгося ΠΎΠ±ΡŠΠ΅ΠΊΡ‚Π°.

    The distinctive paper is detoded to problem of β€œlegitimization” of numerical modelling of wind loads and impacts on buildings and structures. General information about computational fluid dynamics (CFD) and its development prospects is presented. The main advantages and disadvantages of numerical simulation compared with tests in wind tunnels (wind tunnel tests) are considered. Besides, information about the second modification of corresponding Russian design codes (SP 20.13330.2016 β€œSNiP 2.01.07-85* Loads and effects”) is provided. Prospects for the further development of numerical modelling and its applications for solution of problems of construction aerodynamics are given.Настоящая ΡΡ‚Π°Ρ‚ΡŒΡ посвящСна Π°ΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½Ρ‹ΠΌ вопросам, связанным с Β«Π»Π΅Π³ΠΈΡ‚ΠΈΠΌΠΈΠ·Π°Ρ†ΠΈΠ΅ΠΉΒ» числСнного модСлирования Π²Π΅Ρ‚Ρ€ΠΎΠ²Ρ‹Ρ… Π½Π°Π³Ρ€ΡƒΠ·ΠΎΠΊ ΠΈ воздСйствий.

    The paper contains analytical overview of the most important unique/critical objects and the computational analysis problems of the mechanical safety, carried out by the team of Research & Development Centre StaDyO (StaDyO R&D Centre) researchers for the last two years (2016-2018). Corresponding complex coupled problems of continuum mechanics were solved with the use of contemporary methods and models of numerical modeling (nonlinear models, coupled problems, substructures, submodeling, etc.), implemented in verified software complexes. Some of these results are briefly considered and analyzed. Conclusions about the main directions of further research and development are presented as well.
