The chapter provides materials for the development or improvement of means of passive protection of buildings and engineering structures against the negative impact of such climatic loads as wind and snow. The effectiveness of the decisions made regarding the form and place of installation of protective structures is shown on the example of the infrastructure facilities of the Ukrainian Antarctic station “Akademik Vernadsky”. Based on simulation, a study of the effectiveness of the use of means of protection of a vertical cylindrical tank against the influence of wind load was carried out. It is shown that if it is necessary to protect this critical object of the power infrastructure of the station from the action of direct wind load from one direction, then it will be more appropriate to use a deflector. It is shown that if it is necessary to protect the tank in a wide sector, then wind barriers should be used. Based on simulation, a study of the effectiveness of the use of means of protection of civil infrastructure objects against the influence of wind load was carried out. It is shown that when solving the task of reducing the impact of negative pressure on the roofs of buildings and engineering structures, the considered wind protection barriers showed partial effectiveness: the changes made to the air flow are local, therefore, for complete protection, it is necessary to use barriers with a long length, which is economically unprofitable and technically difficult due to the features of the landscape. It was determined that to solve the problems of snow transfer through creeping and saltation mechanisms, it is possible to use wind and snow barriers in the proposed locations on the terrain. It is shown that to partially compensate for the suspension mechanism and the “tsunami” effect, it is necessary to consider the issue of partial or complete reconstruction of the “Akademik Vernadsky” station. Graphical dependences were obtained in the form of fields of air flow velocity and its pressure (positive and negative), which establish a relationship between the efficiency of the considered means of passive protection and their geometric characteristics (foundation, cross-sectional shape, angle of inclination, etc.), installation location or air flow speed. Based on the research results, effective multi-level means of passive protection of structures that are under the influence of high climatic loads can be developed.
