“…Furthermore, there is no regulatory section addressing the specific use of vulnerability functions for masonry houses. This has led other authors, such as Gonzales, Rodríguez, and Romero [2,29,30], to utilize vulnerability functions from other parts of the world for their risk assessments.…”

“…The state of BC is located in a tectonically active zone. The region is subject to high seismic activitydue to its proximity to seismogenic zones associated with the interaction of the Pacific and North American plates [2,31]. BC is the eleventh most populous state in Mexico and is located in the northwest of the country.…”

The north of the state of Baja California (BC) is located in one of the regions of Mexico with a high seismic risk. The predominant infrastructure in the city of Tijuana consists of reinforced masonry housing structures, making it crucial to understand the dynamic behavior of this type of structure. Using the “Vulnerability Modeller’sToolKit” (VMTK), fragility functions were obtained for low, medium, and high levels of seismic design. It was found that the probability of achieving or surpassing the different damage states (light, moderate, extensive, and complete) is high in low-height housing (1–3 floors) for an expected value of 0.50 g of PGA and in medium-height housing (4–7 floors) for an expected value of 0.5 g of SA (T = 0.5 s).Vulnerability functions were derived, and it was determined that, for a low seismic design level, low-height and medium-height structures, respectively presented loss probability rates of 30% and 44% for an expected value of 0.50 g of PGA and SA (T = 0.5 s). These fragility and vulnerability functions can be used to estimate damage and losses in future risk scenarios, thereby reducing uncertainty in the risk analysis calculations for the city of Tijuana.

“…Among these natural disasters, earthquakes have been the most catastrophic phenomenon, in which more than 750,000 people have lost their life, and the economic losses total more than 787 billion dollars (CRED, 2015) (Wallemacq and Below, 2018). The vast majority of the economic and human losses due to earthquakes are the result of the bad results of man-made constructions (Imjai et al, 2020) (Rodríguez Valenzuela et al, 2020). In this context, accurate studies into the evaluation of vulnerabilities provide an essential tool in understanding both the geographical distribution of seismic risk and the development and implementation of risk mitigation strategies (for example, through the adjustment of structures considered to be excessively vulnerable) (Martins and Silva, 2018).…”

For the evaluation seismic risk, there are evermore complex and elaborate procedures, the functions of fragility and vulnerability a fundamental tool. In the last 30 years, various methods have been developed for the analysis of seismic vulnerability in masonry structures. In this article, some of the most common empirical and analytical methodologies have been revised and are explained in a concise manner, which will help other investigators in the field to decide which method is the most suitable, depending on the available information in the study that is being carried out.
