2r.kazarian@mail.ruAbstract. The article considers the main elements of systematization of scientific research. The purpose of scientific research is a comprehensive study of an object, process or phenomenon, their structure, connections and relations based on newly discovered or known to science principles and methods of cognition, as well as obtaining and introducing into practice of construction reconstruction of objects useful for humans the results of research into technogenic impacts and new methods of organizing labor activity and its elements corresponding to these results. Technogenic is an inherent in technology as an artificial system, direct or indirect impact on a natural system, leading to changes in the parameters of human or environmental functioning; such changes are registered organoleptically (using human senses see, hear, touch, smell, etc.) or revealed in the process of instrumental diagnostics or computer monitoring. Diagnostic models are models of technogenic impacts, the study and use of which allows obtaining information on the causes of the identified problems. Using such diagnostic models, by analogy with dynamic infographic models of monitoring the parameters of the system and its components, dynamic series (sequences in time) of predicted retrospective values of the parameters of man-made impacts are constructed. Visual displays of such dynamic series (infographic models) are known as “trends”.
Key words: Diagnostic models; Dynamic infografichesky models of monitoring of parameters of system and its components; Dynamic ranks (the sequences in time) the predicted retrospective parameter values of technogenic impacts.

Abstract. A method for determining the trackage of asphalt concrete pavements using the modern OKO2 geophysical radar operating in the range of 351700 MHz is being studied. The probability of accurate determination of the thickness of the roadway cover under the conditions of operation of the bridge is being developed. Over the past 10 years, there has been a distinct increase in the intensity of vehicle traffic on Russian roads, which has affected the trackage. The root causes of the formation of ruts are the use (popularization of the use) of studded tires (according to the legislation, studded slaughter can be used for 9 months), destruction of the surface layer of the road surface with anti-icing reagents, destruction of the roadway as a result of the interaction of anti-cing reagents and studded tires, high permissible speed when driving on studded tires, frost heaving, the formation of shear stresses in the asphalt concrete coating layer, poor-quality asphalt composition, heating up in hot weather, an increase in the number of cars in families, insufficient thickness of the road surface and cushions under it, etc. Therefore, there is a need to identify which of the factors and to what extent affect the trackage. To find out, it is necessary to determine the thickness of the asphalt concrete layer with non-destructive (gentle) methods for certain. Based on the received radiogram, the thickness of the asphalt concrete coating was determined with an accuracy of 1 mm.

pgups1967@mail.ruAbstract. Currently, chemical anchors have been actively used in the construction industry. As a result of the analysis of more than twenty organizations, only five organizations fully comply with the definition of “domestic manufacturer” or “Russian manufacturer”, of which four produce chemical anchors based on epoxy, and one based on epoxyacrylate. The research was carried out with chemical anchors made on the basis of epoxy resins at the laboratory base of JSC “Research Institute of Bridges”.
To solve the tasks set, 22 series of tests were conducted, divided into three groups: tests to determine the minimum edge and centerline distances, permissible pulling and shearing loads; checking the susceptibility of anchors to installation and operation conditions; field studies to determine the actual bearing capacity of fasteners in real operating conditions.
Key words: anchor fastening; anchor, chemical anchor, adhesive anchor, injection anchor, coefficient of working conditions, mechanical characteristics, endurance tests, Russia.

The article provides an analysis of the possible use of combined steel-concrete structures for high-rise buildings, new developments of structural forms of columns using tubular concrete are presented. The range of combined column designs used is insufficient, and the proposed innovative solutions are not always economical and have insufficient reliability and durability. Variants of combined steel-concrete and steel-reinforced concrete columns have been developed for use in high-rise buildings, as well as overlapping nodes. The application of the developed technical solutions will reduce the material consumption and increase the reliability and durability of the building frame.

r.kazarian@mail.ruAbstract. In the article, the feasibility and necessity of modeling manmade impacts as an important element of managing the construction reconstruction of objects in order to ensure the competitiveness of the proposed organizational and technological solutions is due to a number of reasons: constant increase in the scale, complexity and interrelations in the systems, which leads to an increase in the complexity of the management objects themselves; increasing uncertainty in knowledge of real manmade impacts due to intentional or accidental distortion of information; the dynamics of changes in political decisions or the economic situation in the country, the legal and regulatory framework for activities; changes in ownership forms and increased responsibility of the owner for the results of activities; moral and physical aging of the active part of production assets and housing; changes in the status of a person in the system, when he is often considered not as a determining component, but as an expendable resource. These reasons increase the relevance of forecasting manmade impacts, planning methods for their accounting and management in order to achieve the required level of competitiveness of the proposed organizational and technological solutions for the reconstruction of objects. The concepts and definitions related to the field of modeling manmade impacts are not established, they are in the process of formation; therefore, there are different versions of definitions of the same concept.

Implementation of a direct dynamic method for design schemes of buildings with concentrated masses in the assessment of anthropogenic vibrationDmitriy K.Sizov1, Associate Professor of the Department of Infrastructure Energy System, Candidate of Technical Sciences

1newfff@mail.ruAbstract. One of the tasks that often arise during the construction of buildings in large cities is the need to take into account the vibration impact caused by the movement of road and rail transport (railway lines, shallow subways). The problem of predicting expected vibration levels in buildings, in the most general form, may require the use of the finite element method to model the “vibration source-soil mass-building” system. One of the most labor-intensive processes associated with this approach is the need to create a finite element model of the building that takes into account the distribution of rigidity and mass characteristics of the designed object.
In engineering practice, there is usually no need for such a detailed prediction of vibration levels, including at the initial stages of design; it is desirable to have the ability to predict expected vibration levels with a model nature of ground vibrations taking into account building models that take into account the most characteristic features of dynamic behavior.
One of the possible ways to solve this problem is to use simplified building models, taking into account the mass properties of walls and ceilings in the form of concentrated masses, the rigidities of walls, columns and ceilings in the form of reduced rigidities of the system. The three-dimensional model of the building considered in the article, in the form of a system of interconnected oscillators, allows for a generalized description of the vibration nature of individual building elements under dynamic impact. To solve the dynamic problem, the direct integration method is used, which allows for step-by-step solutions to be obtained at each subsequent time layer using information about the position of the system masses at previous time steps.
Key words: dynamic models of a building, a system of coupled oscillators, a method of direct integration of dynamic equations, vibration protection of buildings from manmade vibration, design of vibration isolation systems.

The heat and humidity regime of the monument’s air environment, its variability, has a significant, and sometimes decisive, importance for the humidity of the materials of its structures and wall paintings. This influence is proved by the results of studies of the TVR of monuments and comparison with the safety of their materials. The Climate Laboratory of museums and Architectural monuments of GOSNIIR constantly conducts research on this problem in order to create means to normalize the humidity conditions of preservation. Together with the research results of the NIISF specialists, this provides a tool for managing the conditions of preservation of architectural monuments. This approach is of particular importance for church monuments, taking into account the specifics of their use. The article considers a practical example of research and the choice of a method for managing the monument’s climate, taking into account the research results.
Key words: temperature and humidity regime, preservation conditions of wall paintings, microclimate, climate control systems, chemical destruction of the material.
