Changes in the load-bearing capacity of industrial buildings due to damage and degradation of the cross-section
Incoming article date: 11.11.2025Long-term operation of a building and untimely repairs lead to damage in load-bearing structures, such as destruction of anti-corrosion protection, surface corrosion, layered and deep corrosion of metal. In reinforced concrete columns, frequent damage includes cracks along the working reinforcement, concrete chips at the corners with exposure of reinforcement rods, separation of the concrete cover, corrosion of the working reinforcement. In this case, the question arises about the impact of the identified damage on the technical condition of the structure. The survey of production buildings and structures is carried out in order to determine the technical condition of building structures and obtain quantitative indicators of the quality and load-bearing capacity of building elements and the entire building. The article presents the results of calculating the loss of potential load-bearing capacity of a metal column and beam, and also discusses the process of degradation of a reinforced concrete cross-section and the loss of load-bearing capacity of a column due to the development of corrosion of reinforcement rods. The article will be relevant for specialists and experts in the field of industrial safety expertise and building and structure inspection.
