Seismic Vulnerability and Rehabilitation Strategies for Industrial RC Structures

The catastrophic impact of building collapses or severe structural damage during significant earthquakes has led to considerable economic losses, serious injuries, and tragic loss of life. Retrofitting has emerged as a globally recognized solution, particularly for critical structures such as historical buildings and aging constructions that have experienced degradation over time. Unlike traditional repair and rehabilitation methods, retrofitting offers a more effective and practical approach, markedly enhancing the strength, resilience, and overall lifespan of structures. This paper provides a detailed investigation of seismic retrofitting techniques, with a particular focus on reinforced concrete (RC) industrial buildings, which constitute a substantial portion of the existing built environment. The study delves into various retrofitting methods, categorized primarily into two groups: concrete column jacketing, which bolsters the durability and load-bearing capacity of columns, and steel bracing, which enhances structural performance against lateral loads. These techniques are essential for maintaining the safety and integrity of structures, especially in regions prone to seismic activity. By addressing structural vulnerabilities, these retrofitting strategies significantly reduce the risk of catastrophic failures and bolster community resilience. This research offers valuable insights into the field of structural engineering and disaster resilience planning, highlighting the importance of understanding and applying these strategies. Through informed implementation, engineers and policymakers can improve the seismic resilience of existing buildings, thereby mitigating the detrimental effects of earthquakes on both human life and infrastructure.
