On the unloading action of torques in beams reinforced concrete coffered floors

Mozgolov M.V., Kozlova E.V.


The purpose of this work is the qualitative and quantitative identification of the unloading effect in the beams of direct coffered floors from the action of torques. To solve the problem in the computer complex SCAD, the bending and torsional moments in the beams of a direct coffered floor hinged along the contour with a plan size of 8.0 × 8.0 m with different widths of the beams installed with a step of 1.0 m were determined. As a computer model, a rod finite element model of beams of rectangular section with a direct application of a linear load to them according to the law of a triangle was used, as the most accurate finite element method. Analytical calculation of the structure is carried out. The calculation data of computer models showed that as the width of the beams increases, the torques in them increase, while the span bending moments decrease. The width of the support contour beam affects the support bending moment of the span beams, which occurs at the point of their joining. The paper presents graphs of the dependence of the values of the span bending moment, the support moment and the torque on the width of the caisson beams. The analytical method for calculating coffered floors does not take into account the rigidity of the support contour, the presence of torques in the beams, their effect on bending span moments and deflections of the structure. This is one of the reasons for the discrepancy between the data compared by the researchers.

Phytoremediation potential of aquatic plants to tetracycline in Eastern Siberia

Timofeeva S.S., Tyukalova O.V., Ulrikh D.V.


The current status of the environment pollution with tetracycline antibiotics is considered. It is demonstrated that big-scale and often unauthorized use of tetracyclines in veterinary practice leads to their accumulation in foods of animal origin and in natural environments, resulting in endocrine disorders, chronic toxicity, and development of antibiotic resistance. The existing treatment facilities as a rule do not ensure the removal of antibiotics from wastewater, so these transit through the treatment system, directly enter water bodies (rivers, lakes), and pose a threat for water users located downstream. To block this path of antibiotics spread, advanced treatment systems can be used, such as phyto-engineering treatment facilities with growing of aquatic plants with high phytoremediation potential for antibiotics. It has been found that aquatic plants are capable of eliminating tetracycline from water medium. It has been proposed to consider phytoremediation as one of reasonably-priced solutions for removing antibiotics from water medium.

Hydromechanical method of aeration of open water bodies under conditions of urban development

Orekhov G.V.


Open water bodies in areas with dense urban development experience an increased anthropogenic impact and, therefore, need restoration work, reconstruction and maintenance of the normative sanitary state of water. Many of them are closed, without flow. The article discusses technical approaches for maintaining the oxygen regime of urban water bodies, which is the most important indicator that determines the normalization of biological processes occurring in the aquatic environment. At present the only way to maintain the necessary hydrobiological characteristics of water bodies in urbanized areas is to create special hydraulic systems for artificial jet aeration of water bodies and circulation currents in such objects.

Principles of biophilic design in the organization of a comfortable space

Butabekova A.S.


This article discusses the principles of biofilm design as a way to change a person’s attitude to the surrounding space. As you know, plants have a positive effect on physical health, efficiency and productivity, as well as the emotional state of a person and participate in the creation of a harmonious interior. The biophilic direction in architecture and design seems to be the most promising, since it corresponds to the most relevant of all modern global trends based on the principles of sustainable development of society. Being a relatively new concept on the interior design scene, it has many advantages that need to be explored. It should be noted that biophilic design is more than just a powerful aesthetic, it is a design method that can improve human health and well-being, as well as the environment.

Ideas of architectural and landscape scenario and quantitative assessment of the aesthetic qualities of the urban environment in the process of its perception

Temnikova E.A.


The role of quantitative and qualitative assessment of the aesthetic properties of the urban environment in the process of its perception is considered and the role of modern architecture in promoting these changes is determined. The design of the environment is considered as a subjective concept and the assessment of the aesthetic qualities of the urban environment is also perceived subjectively. “Local” art is one of the many trends that emerged in the second half of the twentieth century, but it is of particular importance for the recognition of urban space. Most modern architects, landscape architects, environmental designers and urbanists attach great importance to mapping the architectural context, and artists emphasize individual expression, autonomy and universality of the arts. Conservation is a balance between preserving the quality, significance and special character of the historically established territory. The role of urbanists and specialists in the field of conservation of natural resources is to ensure a balance of the old and the new.

Frost protection of the mouth of the exhaust tower of the cooling tower with natural draft

Demina Y.E., Kudinov A.A.


The article presents the results of numerical simulation of the protection system of the mouth of the exhaust tower of a cooling tower with natural traction from freezing. To prevent the formation of ice, it is proposed to install an atmospheric air supply system at the mouth of the cooling tower, which ensures the creation of a protective boundary layer at the inner wall of the cooling tower and allows you to separate the warm moist air of the cooling tower from the cold walls. To test the possibility of using such a scheme, a numerical simulation of the process was performed using the k-SST turbulence model. The use of an additional air flow injection system makes it possible to increase the efficiency and reliability of a naturally aspirated cooling tower and a thermal power plant as a whole. Modeling of the cooling tower protection system from the formation of ice showed the possibility of using this scheme in all ranges of outdoor operating temperatures.

Pressure distribution study in cone slot gap drives of electric power systems

Krestin E.A., Zhilnikov V.B.


The distribution of pressure in the conical slotted gaps of drives of electric power systems has been studied. A general expression is found to determine the pattern of pressure change along the flow of a viscous fluid in the gaps of non-contact seals, and special cases are also considered. For a narrowing gap, the maximum pressure will be in the section with the smallest gap. In this case, the plunger will tend to take a coaxial position. In the expanding gap, the maximum pressure will be in the section with a larger gap, so the plunger will be pressed against the wall of the sleeve by the forces of unbalanced pressure. With an eccentric location of the plunger in the sleeve, the pressure in the gap will change. Moreover, the uneven distribution of pressure increases as the eccentricity increases. With a larger taper of the slotted channel and with a constant inlet gap, the nature of the pressure change along the slot differs significantly from the linear one. If the flow and the plunger move in the direction of the increasing gap (expanding gap), then the plunger is pressed against the wall of the sleeve by the forces of unbalanced pressure. In this case, the contact surface of the plunger pair is destroyed, which leads to scuffing and failure of the units.
