1. Structural risk analysis issues

Methods for analyzing the reliability of structures first appeared in the context of risk management in the 1950s. In the past, the safety of structures was based on the traditions of journeymen and on feedback from structural design and behavior. Since the 1960s-1970s (since the 1980s in France), significant work has been carried out on structural strength, material degradation laws, loading and the performance of non-destructive testing, and structural reliability methods and associated numerical methods have developed
