During building and construction maintenance, corrosion of reinforced concrete bearing structures may occur due to various factors (errors at the design stage, exposure to external aggressive media, insufficient construction control, etc.). Thus, there is a need to develop certain methods of calculation of structures which take into account the effect of damage on load-bearing capacity and stability. To date, there are engineering methods for calculating corrosion-damaged reinforced concrete elements under the action of static and dynamic loads. However, there is a need to assess the bearing capacity of corrosion-damaged structures under seismic effects, both in verification calculations of existing buildings and at the design stage of buildings subject to corrosion of reinforcement due to increased aggressiveness of the environment or other negatively influencing factors. The paper discusses the developed methodology and test program for evaluating the seismic resistance of reinforced concrete columns at various levels of reinforcement damage. This test methodology is developed with the recommendations of GOST 27751. To ensure the reliability and mechanical safety of buildings and constructions, it is necessary to perform calculations using data from experimental studies of real building structures or models of construction sites and connection nodes.
