Peru is a country with high seismic activity due to its location in the area known as the 'Pacific Ring of Fire', which makes the construction of safe buildings a fundamental need. However, the large amount of informal construction in the country generates structural pathologies, making buildings vulnerable to earthquakes. Lack of knowledge about the consequences of structural pathologies in buildings can lead to ignoring real dangers and increasing the risk of damage and loss of human life in the event of an earthquake. It is necessary to understand that structural degradation can decrease its ability to resist an earthquake. The research presents an initial study on the structural degradation of reinforced concrete buildings affected by structural pathologies. The configuration of reinforced concrete frames with up to six levels and six spans affected by pathologies such as carbonation, freeze-thaw cycles, corrosion, porosity, and alkali-silica reaction was considered in three levels of pathological severity (mild, moderate, and severe). Corrosion, carbonation, and porosity were identified as the most likely occurring pathologies in our country. A total of 96 frames were analyzed. Structural pathologies were modeled based on the results obtained from experimental research published in scientific papers. The structural analysis method used was nonlinear static analysis ('pushover'), through which capacity curves were obtained which related the base shear with the maximum displacement of the structure (work by external forces). Subsequently, the obtained results (capacity curves) were compared, and the behavior of the structures affected by different structural pathologies was determined. The research concludes with the determination of the percentages of degradation of the structural capacity.
