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

Abstract

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.
