Subject: studying the main directions for increasing durability and safety of unique, technically complex objects on the example of the Kayrakkum HPP. The peculiarity of operation of this kind of structures is the specificity of physical, chemical and mechanical factors that negatively affect their durability. However, complexity of the technical solution execution does not allow us to completely replace these structures after expiration of their standard service life. Taking into account the uniqueness of the HPP, the programs for the operational suitability restoration are individual. The main problems of reconstruction are considered, which consist in the necessity of, firstly, increasing the station’s productivity, and secondly, ensuring the stability of the dam to erosion and scours. Research objectives: the goal of the study was to develop proposals for improvement of operational suitability of the Kayrakkum HPP based on data on the technical condition of its main units, buildings, and rockfill dam. Materials and methods: in the process of long-term operation, due to filtration processes, seismic influences, the performance parameters of buildings and structures of hydropower plants deteriorate, which negatively affects the reliability of their operation. Therefore, based on the methods of mathematical statistics, data on the projected flood were analyzed. The data on the technical condition of the main HPP equipment were also analyzed and the main directions of its modernization were determined. Results: an assessment of the probability of destruction of the dam showed the need to strengthen it to reduce water filtration. A comparative analysis of possible options for reconstruction of the Kayrakkum HPP has shown the need for an integrated approach that will allow us to solve both the issues of ensuring safety requirements in accordance with international quality standards and enhancement of the plant’s capacity to increase the generation of electricity, the demand for which has increased over time. Out of four technological solutions to reduce filtration into the body of the dam, an option of the central diaphragm from the secant bored piles has been chosen as the least affecting the production cycle of the entire complex. Conclusions: the results of this work can be used when clarifying the repair work organization project to link the technological cycles in such a way as to reduce the losses in generation of electricity caused by execution of works on reconstruction.

Tower cranes are one of the main tools for execution of reloading works during construction. Design of tower cranes is carried out in accordance with RD 22-166-86 “Construction of tower cranes. Rules of analysis”, according to which to ensure stability it is required not to exceed the overturning moment upper limit. The calculation of these moments is carried out with the use of empirical coefficients and quite time-consuming. Moreover, normative methodology only considers the static position of the crane and does not take into account the presence of dynamic transients due to crane functioning (lifting and swinging of the load, boom turning) and the presence of the dynamic external load (e.g. from wind for different orientations of the crane). This paper proposes a method of determining the stability coefficient of the crane based on acting reaction forces at the support points - the points of contact of wheels with the crane rail track, which allows us, at the design stage, to investigate stability of tower crane under variable external loads and operating conditions. Subject: the safety of tower cranes operation with regard to compliance with regulatory requirements of ensuring their stability both at the design stage and at the operational stage. Research objectives: increasing the safety of operation of tower cranes on the basis of improving methodology of their design to ensure static and dynamic stability. Materials and methods: analysis and synthesis of the regulatory framework and modern research works on provision of safe operation of tower cranes, the method of numerical simulation. Results: we proposed the formula for analysis of stability of tower cranes using the resulting reaction forces at the supports of the crane at the point of contact of the wheel with the rail track.

Subject: friction piles are calculated by the first and second group of limit states. The article describes a new method for friction pile design by the second group (by settlement) of limit state in relation to the pile foundations of buildings and structures in the urban area and in the design of extensions to existing buildings in which the value of settlement is limited or unacceptable. A new method of piles settlement calculation is different from existing method by the Building Code SP 24.13330.2011. The method is based on a new approach of the pile behavior in soil base, which is different from the existing regulations and science papers. Research objectives: the new method of pile settlement calculation is presented with the purpose of clarifying the calculation of pile bearing capacity unlike an existing method in the Building Code (SP 24.13330.2011). The basis of the design is a new idea of the pile behavior in the soil base, which differs from the existing approaches. Materials and methods: the method consists in the formation of the pile settlement only as a result of pile shortening from the compressive force by the deformation of the pile material. Results: the design equation is presented for calculation the pile settlement caused by the pile material deformation. The condition for determining the pile length is presented, which provides the pile settlement only due to the pile material deformation. Conclusion: such approach of the pile settlement calculation is necessary for the design of extensions to existing buildings, as well as new structures near existing buildings, in which the settlement value is already close to the ultimate value of settlement. The article presents the examples of pile settlement calculations obtained by various methods (including the method of the Building Code SP 24.13330.2011) for comparison of the results. The article can be used in the piles design and in the formation of new design standards for pile foundations of structures and machines.

In the proposed article, the behaviour of a foundation slab resting on the linearly deformable bed and characterized by the modulus of deformation variable in x- and y-axis directions is considered. The modulus of deformation and the load distribution are based on a regular pattern that features the following parameters: modulus of deformation mean =25МРа coefficient of variation =0,2, load distribution mean 0,5 МРа; coefficient of variation =0,1. Correlation coefficients between 1, 2...=0As a result of the research, the authors have identified the empirical deflection to approximate the theoretical load distribution. The research has demonstrated that both deflection and slope values follow a regular load distribution pattern. If the deflection value exceeds 20 cm and the slope value exceeds 5cm, the structure fails. Therefore, the theory of probability may be applied to assess the probability of failure of any structure.

In connection with increasing demand for providing quality medical services, the technologies and systems for safe work of personnel began actively developing in the world. Unfortunately, at the present day, physicians have to deal with the microorganisms of different danger level, therefore, for the purpose of safety of personnel and patients, the detailed analysis of air environment is needed as there can be a risk of introduction of infection for people. Currently, incidence rate conditioned by microbiological contamination of air environment of rooms remains at a high level. Prevention of disease dissemination is a basic task of the process of air discontamination. Air contamination provides the decrease of incidence of contagious diseases and complements the obligatory compliance with existing sanitary norms and rules for space planning, furnishing and maintenance, primarily medical and preventive ones. One of the ways of contagious diseases dissemination is aerogenous (respiratory), related to the main method of transmission of respiratory diseases, such as influenza virus infection, tuberculosis. It is related to the fact that airborne bacterial aerosol is constantly suspended in the air volume of rooms due to air motion (convections), that increases contamination rate.

The authors consider several problems of radiation control in the process of construction operations. The authors describe sampling of radon, a radioactive gas which can be often found in the environment, and therefore, it may be the reason for cancer diseases. Residential houses represent the main source of ionizing radiation, given the fact that the time spent at home accounts for about 60% of the overall radiation exposure. Safe radon content values for residential and office buildings are provided in the article. Maximal acceptable doses of radiation, emitted by natural sources, in respect of office personnel (below 5 mSv per year) and residents (below 1 mSv per year) are identified. Maximal acceptable doses are regulated by the Russian Standard of Radiation Safety.Difficulties accompanying radiation control in the course of construction operations are described in the article. Field measurements of radon emissions from the soil surface have been taken in Russia for over 10 years; no other country has taken any measurements of this kind.The highest efficiency of radon protection is achieved at the stage of design of buildings. If regulatory requirements are honoured at the design stage, radiation protection turns a lot cheaper than elimination of high concentrations of radon inside existing buildings.

Safety and reliability factors, assumed in Russian and international standards, as well as the main provisions of design of offshore oil and gas structures are considered in the article. The reasons for structures destruction are classified. The analysis showed that the main design provisions and methodology of calculations related to provision of safe and reliable operation of offshore oil and gas structures by different standards are not fundamentally different: the required degree of reliability of the structure is set depending on the social and economic consequences of possible hydrodynamic accidents; calculations are based on the limit states design method using partial safety factors; etc. However, the factors accounting the degree of the structure reliability, partial safety coefficients and load combinations coefficients differ in different standards and methodologies.

In this paper, the authors propose an approach to identification of the optimal structure of an automatic control system using CAD. The approach is based on the introduction of an abstract characteristic of reliability of control systems to take account of heterogeneity of versatile engineering systems designated for sustainable buildings.Application of the proposed method of selection of an automatic control system designed for CAD algorithms helps determine reliability as an abstract characteristic of an automatic control system.Integration of the above algorithm into the CAD system will ensure selection of automatic control engineering systems of buildings with account for the critical values of control systems with reference to particular buildings.
