A Reliability‐Oriented Approach to the Ensuring Longevity of critical Infrastructure

Abstract The reliability of engineering structures and infrastructure is crucial for their long‐term functionality. Extending the lifespan of concrete structures in critical infrastructure is essential for sustainability and resilience. This research explores how reliability ‐oriented safety factors, can achieve this. By analysing normative design rules, particularly variability measures like the coefficient of variation (COV) and standard deviation of materials, the study identifies significant safety margins that can be utilized to extend service life. It demonstrates how reliability‐based methods can integrate these margines into quality control systems. The research highlights the importance of statistical parameters, such as means, standard deviations, and fractile values, in improving assessment precision and reliability. Findings show that semi‐probabilistic safety concepts and adherence to standard design and conformity regulations can significantly increase service life. This approach enhances infrastructure durability and safety while promoting sustainable development by optimizing existing engineering assets.
