This article gives a brief historical digression about the formation of architectural and building aerodynamics as a separate branch of the construction science. The main methods and approaches to the solution of problems of architectural and building aerodynamics are listed; the classification of problems of aerodynamics of structural steel according to the studied objects is given; main peculiarities of the research in selected areas are briefly indicated. The aim of the work is to systematize existing approaches to assessing wind impact on structural steel taking into account some modern international requirements, as well as to choose the optimal method for solving this problem in relation to various structural steel. It is established that, currently, the study about wind impact is especially important for high-rise buildings, structures, and structural steel nonresistant to dynamic loads (long span bridge conduits, gins polarized, thin-shell tubes, etc.), as well as for residential estates with restrained urban conditions. It is necessary to carry-out these aerodynamic studies at the designing stage for the above objects because it is directly related to the issues of reliability and safety.

The article deals with the composition of the landscape and building on the basis of the laws of aerodynamic resistance of objects to the wind flow and the resulting physical effect of sail. The application of landscape-visual assessment based on windage properties as a criterion for the development of the architectural and town-planning appearance of buildings is presented. Windage is studied as a physical phenomenon arising in landscape forms, buildings, loose materials, surface and vegetation of the relief. Similarities are found between the silhouettes of windage ships and urban buildings. It is revealed that in the architectural qualification the center of the sail and the center of the lateral resistance of the object can help assess the relative position of the elements of the landscape and the appearance of the building in order to achieve compositional integrity. Thus, a technique for assessing visual appearance based on a system of visual moments of sailness with respect to the object’s observation center has been developed. The influence of high-rise buildings on the conditions of the active surface for human stay on domestic and foreign examples is analyzed. Among the described objects there are high-rise buildings on Novy Arbat in Moscow, the sculpture “Motherland Calls!” In Volgograd, Spinaker Tower in Portsmouth (United Kingdom), Burj Al Arab Hotel in Dubai (United Arab Emirates). It is noted that to assess the compositional integrity of the observed landscapes by visual windage, photographs from the ground level and significant heights of window openings are used. It is proposed to use this to assess the existing types and panoramas, for which they need to capture a photo or video of planar or volumetric images, while performing editing to establish the adequacy of visual perception of a person in real conditions. In conclusion, the result of the study reveals the application of the method of assessing visual windage to determine the proportional unity of the external volume of the building with the environment. On this compositional characteristic, the creation of an artistically completed whole landscape is based, which increases its aesthetic and economic value.

The article discusses the interaction between the wind regime and the landscape. Examples of objects of landscape architecture in high-tech and science-intensive spheres, such as the launch pad of a spacecraft, are given. Wind protection is represented as a result of work on wind power engineering and a means of increasing bioclimatic comfort. The terms of landscape architecture are disclosed and mutual influence on the climate and impact on woody-shrub vegetation and field crops are analyzed. The phenomenon of air permeability for optimal operation of windproof structures and orientations of geoplastics and dendroplastics is described. In this paper, a classification of terrain types is described with a description of their elemental composition, as well as various categories of landscape. The proposal to consider the landscape as a territorial complex, and landscape buildings, landscape-architectural structures as objects of landscape architecture possessing properties of wind protection and air permeability was introduced. Thus, the concept of a landscape-architectural complex as a single group of landscape-architectural objects located on the territory and connected by a common system of communications, functions, technical elements and a visual image is formulated. Further research is based on the rationale for the use of the term ensemble in relation to the objects of the landscape and architectural complex and the identification of their design and planning features that can affect the parameters of wind protection and air permeability. The paper concludes that frequent coincidence of favorable for the fauna wind regime and mimicry of landscape architecture objects. The combination in the landscape of functions for wind protection and aesthetics is analyzed with analysis of such elements of landscape architecture as hedges and windproof properties of green plantations. In the work examples of wind engineering small architectural forms are shown in the form of sculptures moving from air streams, which also change the speed and direction of the wind. All this is generalized in further directions of research within the framework of the designated terrain theme, bioclimatic comfort and wind protection.
