Risk and reliability analysis is integral to civil engineering decision$-$making processes, particularly in assessing the safety and performance of infrastructure systems under uncertain conditions. Develop a comprehensive theoretical framework elucidating principles of risk assessment, including probabilistic modeling techniques, failure mode and effects analysis $($FMEA$),$ and reliability$-$based design methodologies. Explore theoretical approaches to quantifying and managing risks in civil engineering projects, considering factors such as uncertainty, variability, and stakeholder preferences, with the aim of enhancing project resilience and sustainability.
