The article shows studies of bending basalt fiber reinforced concrete elements with pre-stressed glass composite reinforcement under static and short-term dynamic effects. Main results of numerical and experimental studies are presented. It is experimentally established and theoretically confirmed that a significant increase in the strength and crack resistance of the normal sections of concrete bent elements is observed when using basalt fiber reinforcement and pre-stressed glass composite reinforcement.

“…One of the most common options for strengthening concrete structures is the reinforced concrete collar, carried out by joint grouting of damaged structures with concrete and the installation of an additional reinforcement frame. It is known that in reinforced concrete, due to its nonlinear properties under short-term dynamic loads, complex processes occur (Plevkov, 1996;Baumung et al, 2001;Plevkov et al, 2004;2008;Sarkisov et al, 2020;Venkiteela et al, 2013;Belov et al, 2016;Dong et al, 2017;Odnokopylov and Sarkisov, 2017;Gao et al, 2017;Chen et al, 2017;Demyanov and Kolchunov, 2017;Savinykh et al, 2018;He et al, 2020;Likhov et al, 2020;Orton et al, 2021). Therefore, the design of reinforced concrete structures under such types of impact is a scientific problem.…”

The relevance of the subject matter is conditioned by the technical complexity of the oil and gas facilities due to the increase in the volume and rate of raw materials production, which may be affected by shock-wave loads in emergency situations. The causes of the impact can be explosions, heavy cargo falls, terrorist attacks, natural and anthropogenic disasters, etc. These situations are very likely to cause significant damage to the building structures of industrial facilities, which necessitates their reinforcement. For further safe operation of the facility, reinforced structures must have survivability under repeated impacts no less than before the reinforcement. Given the fact that the survivability of buildings is a complex characteristic influenced by many factors, and it itself is a component of the security of a hazardous production facility, research in this area is topical. The purpose of the study is to test the developed method for assessing the survivability of a building structure under short-term shock-wave load based on the energy parameter and to analyze the results obtained in the context of assessing the security of critical oil and gas facilities. Research methods: Measurement of accelerations, deflections, and loads by strain measurement methods, graphoanalytical method of study using the Microsoft Excel software. A method for assessing the level of survivability of a building structure under shock-wave loading for critical oil and gas facilities using the survivability coefficient is developed. Using specific tests of conventional and cage-reinforced bending concrete elements for short-term dynamic load, the values of the specified coefficient are obtained. The values are compared and conclusions are drawn.

The methods of modeling the process of choosing methods and means of vibration protection for building structures with moving loads are considered based on a review of the literature on this topic. Structural analysis of vibration protection devices for building structures was carried out. Various options for reducing the negative impact of external influences in each specific case are proposed. Currently, building structures and buildings in general are under the influence of a significant number of sources of undesirable vibrations, both natural and technogenic. For example, in residential and public buildings the number of pumps, fans, air conditioners has increased, a large number of different machines, mechanisms and equipment is used. In the process of construction, as well as repair and reconstruction, the building is subjected to shock, mass (static), vibration and other effects. The increase in the number of transport and transport networks (which themselves are systems with moving loads) passing in the immediate vicinity of buildings and structures also affect them, both acoustically and mechanically. High-rise buildings are exposed to the force of the wind, buildings located in seismically hazardous areas - to seismic effects. It should be noted that the vast majority of vibration sources can be reduced to moving loads. Thus, at present, the task of reducing the impact of moving loads on building structures, and the resulting adverse factors (noise, oscillation, vibration, etc.) for comfortable living and human life is relevant. To protect buildings and structures from various types of moving loads and adverse factors, protection systems are provided. The system of building structure protection from various negative impacts can be conditionally divided into built-in and special. For example, fixed building structures can be designed in such a way that they are tuned mass dampers that protect high-rise buildings from the force of wind; engineering systems provide for the installation of noise suppressors on air ducts, noise-absorbing panels, the use of vibration isolation, vibration bases, floating floors, etc. when installing various equipment. Special measures may include the installation of special protective devices on pipelines, such as resonant wave process stabilizers, magnetorheological devices, etc. To select the most appropriate means of vibration protection for building structures with moving loads, it is proposed to use the methods of functional-structural analysis.
