“…Various empirical methods have been developed based on resilience concepts or field experiences to evaluate engineering systems. Empirical methods are divided into definite 9,[32][33][34][35][36] and probable [37][38][39][40] sections, each being used for the description of the behavior of static and dynamic systems. In the definite methods, the uncertainties such as the probability of disturbance are not considered.…”

The use of resilience during the mining period by guaranteeing the safety and performance of the systems greatly helps the managers and engineers with their decision-making and designing different systems. During the last two decades, various studies have been conducted in this regard. However, the analysis of underground coal mining systems’ resilience has been rarely addressed by these studies. The present study aims to provide a quantitative index for resilience in the environment of underground coal mining operations based on the risk factors. To do so, in a case study of Tabas Mechanized Coal Mine, the Failure of shearer data and the stoppages caused by it (for 2 years and a half, from March 2017 to June 2019) were studied to analyze the system’s resilience. Then, the experts were surveyed. After collecting and categorizing the data, the data analysis calculations were done for indicators of reliability, maintainability, supportability, organizational resilience, PHM system efficiency, and economic resilience. Finally, a new quantitative index named the “Shearer System Resilience Index” was introduced. The results indicated that resilience is reduced over time. They also shows that in order to improve resilience, project managers should pay more attention to these indicators, especially the indicators of maintainability, and organizational resilience. Therefore, regarding the scope of the data investigated in the current study, the use of Failure of Shearer data-based risk factors and experts’ opinions for the analysis of resilience in the case study is strongly recommended.

“…Li (7) proposed an optimized macroseismic analysis, integrating the traditional macroseismic intensity scale and evaluation models of resilience and empirical vulnerability of regional buildings. In another work, Li (8) studied the seismic vulnerability of regional group structures, establishing empirical vulnerability matrices of six building groups in different seismic intensity zones.…”

The church of San Lorenzo in San Buono (Italy) is unique in the local landscape due to its technical, and architectural features. The building, whose construction dates from the 14th century to the mid-20th century, was realized by the most important designers in the region. The bell tower is an element characterized by refined neoclassicism and testifies to a remarkable episode of the permanence of the neoclassical style in Abruzzo until the first decades of the 20th century.The present study illustrates both a technological-constructive analysis of the building and an assessment of the seismic risk of the bell tower, to present an important point for the knowledge of the artefact with regard to possible conservative restoration works. The seismic risk analyses are carried out for two different structural configurations and two different typologies allowed by the Italian building codes for monumental masonry buildings: simplified linear and non-linear static. The study illustrates how the presence of the adjacent structure significantly alters the structural behavior of the masonry tower, both in terms of displacement and propagation of the crack pattern. The differences in the results of the non-linear calculation and the expeditious methods suggested by the standard are highlighted as well.
