Abstract
Reinforcement corrosion is an increasingly serious issue worldwide. The structures gradually lose their load-bearing capacity, reliability and service life of the buildings decrease. Humankind should monitor and solve the problem of corrosion. From this reason, the research is focused on effect of corrosion on the structures not only in Slovak Republic. This study continues the previous work (Strieška et al., 2018), where were investigated corrosion maps of carbon steel (reinforcement in Slovakia between years 2004-2017. A dose-response function was used to evaluate the effect of corrosion on steel rebar. Input data for the corrosion models were obtained from the Slovak hydrometeorological institute database. Corrosion losses for individual monitoring stations across the Slovak Republic were determined by calculation. Corrosion maps were visualizing in programs Gimp and Qgis. The results were processed in the coordinate system WGS 84. The results are corrosion maps of corrosion losses per year between years 2017-2024 in Slovak Republic. Following, the effect of corrosion was applied on the structural beam subjected to bending and exposed in the aggressive corrosion environment. These examples were developed for the monitoring stations, where corrosion risk was the highest, and lowest in Slovak Republic and for the station Žilina. The graphs illustrate expected reduction in beam capacity subjected to bending caused by the corrosion of reinforcement over a 100-year period. The research demonstrates that the effect of corrosion significantly affects the structural reliability and durability. The analysed beam demonstrates reduced load-bearing capacity and does not achieve the required load-bearing capacity over a 100-year period.
