This article divulges the outcomes of theoretical investigations into non-uniformly damaged reinforced concrete beams, employing the LIRA-FEM software suite. The manifestation of defects and damages poses operational risks for buildings and structures. The objective of this study is to scrutinize the consequences of irregular damage occurrence in reinforced concrete beams, holding significant practical relevance for the determination of the stress-strain condition in reinforced concrete elements. To facilitate these theoretical inquiries, finite element modeling within the LIRA-FEM software suite is employed. Through the modeling results, stress levels were juxtaposed against ultimate stress thresholds, elucidating the deformability of unevenly damaged reinforced concrete beams. The study's significance lies in its potential to enhance the safety of building structures, mitigating risks during operational phases.
