“…The essence of the approach is based on the principle of limiting the collapse of the structure as a whole by dividing it into separate independent or weakly interconnected independent substructures, each of which has its own structural system to ensure strength and stability [15][16][17][18][19][20].…”

“…To limit the magnitude of possible destruction, expansion joints are provided between segments of several adjacent spans, constructing each segment as a separate structural unit [24][25][26][27][28][29][30][31]. In the vertical direction, communication floors or powerful crossbars of interfloor ceilings are arranged [20][21][22][23][24][25].…”

“…They rely on the term «general structural integrity» M. Fintel and, analyzing the rules for designing US standards, identify the main requirements that increase the resistance of structures in [20] for describing this method: good building plan; a complete communications system; changes in the directions of spans in the ceilings; distribution of internal load-bearing elements; use of a hanging system in ceilings; the action of the walls as beams; systems with excessive static indeterminacy; additional fittings for the perception of shock explosive loads; structures insulation.…”

“…In addition to the above-described methods of protection against progressive destruction, mainly associated with an increase in the strength of individual elements and their knots of their conjugation, structures as a whole by enhancing connectivity and continuity, the opposite approaches have also been developed, called «segmentation» [20][21][22][23][24][25][26][27][28][29][30][31], or the method controlled collapse.…”

The structural reliability of the building ensures the building safety as a whole and the safety of the population, therefore the issue of ensuring reliability arises primarily in the design process. Buildings must be protected from destruction during all types of force, as well as in the case of load-bearing structures destruction as a result of emergency. Emergency impact on an object is an unregulated impact that is created as a result of an object getting into a special situation and can lead to its accident. The causes of structures progressive collapse are considered in this article. The main methods and methods of protecting buildings from progressive destruction are given. The calculation analysis of the monolithic reinforced concrete building frame for progressive collapse according to the method of possible damage is performed. There are many calculated and constructive proposals for solving the problems of counteracting the progressive destruction that can be divided into three categories: secondary protection measures, indirect design and direct design. In this article the resulting reinforcement of structural elements is determined taking into account the structural requirements for the continuity of longitudinal reinforcement, the minimum percentage of reinforcement. They are determined in the necessary places of additional reinforcement depending on the accepted permanent (background) reinforcement of the floors.

“…The structural safety of buildings interests requires ensuring: geometric invariability of the structural scheme at all the stages of their existence (and during reconstruction and dismantling -with the additional connections help), a stable stress-strain state and position in space and time of all supporting structures of the building, and survivability of statically indefinite systems. And yet, the common thing is to ensure the strength and stability of individual load-bearing elements of the system and the so-called «redundant ties» despite the different purpose of these conditions [1][2][3][4][5][6][7][8][9]. At the same time, the assessment of structural safety is an obligatory stage of the decision-making procedure on the issues of continued operation or technological reorganization of production, reconstruction, etc.…”

Reserves and exposure assessment of reinforced concrete structures safety while reducing its power resistance

Structural safety of buildings is such an engineering state of the structures operability, foundations, the features of their joint power resistance to expected loads and impacts, taking into account their possible combinations in direction, intensity and mode, which ensures the established functional use with established reliability. The structural safety of buildings depends on design, on compositional and structural solutions, technological measures during construction and operation, which must be provided at all stages of the facility’s existence (construction, operation, repair, reconstruction, dismantling and dismantling). It is necessary to take into account the structural safety parameters of reinforced concrete structures that have received corrosion damage during solving the problems of construction and reconstruction of buildings and structures. Suggestions to quantify the reserves and exposure of structural safety and, accordingly, the reduction in power resistance of corrosion-damaged reinforced concrete structures are presented in this article.
