| Abstract | ||
| Sudden Impact of structural events poses a signiicant threat to life safety and structural stability. In other words, the local failure(s) of structures can lead to the collapse of other members and eventually a partial or total collapse. Impact load is one of the extreme loads that are not usually taken into design consideration because of its high cost to be prevented unless the usage of the building dictates this extra care. Hollow core slabs, while offering advantages in terms of weight and construction eficiency, are particularly vulnerable to localized damage in comparison with other slab systems to localized damage, which could lead to progressive collapse. This research investigates the effectiveness of Fiber Reinforced Polymer (FRP)retroitting techniques in enhancing the impact of resistance of hollow core slabs, aiming to mitigate progressive collapse risks and improve structure resilience. In this paper, the signiicance of FRP retroitting techniques and properties for different types have been discussed and compared, focusing on Glass Fiber-Reinforced Polymer (GFRP) and carbon Fiber-Reinforced Polymer (CFRP). By evaluating various case studies, experimental analyses, and numerical simulations, the effectiveness, durability, and performance of FRP retroitting strategies are examined as well to show the most suitable material for resisting impact load. The indings of this study will provide valuable guidance for engineers and designers in selecting the most suitable FRP material for retroitting hollow core slabs, enhancing structural integrity and safety against impact loading. Furthermore, this research identiies research gaps and potential areas for further investigation, contributing to the development of a more effective and resilient research orientation for enhanced structure systems. | ||
