The structural integrity of steel construction projects is a paramount concern, necessitating rigorous assessment methodologies that have evolved significantly over time. Advanced techniques are now employed to detect and quantify degradation mechanisms such as fatigue, corrosion, and material deterioration, underscoring the importance of integrating numerical modeling with experimental testing to predict long-term performance and remaining service life of steel structures.
