Retrofitting and Strengthening of RCC Structures: Methods, Materials, and Modern Solutions for Enhanced Durability and Seismic Resilience

  • Unique Paper ID: 189786
  • Volume: 12

  • PageNo: 4623-4637
  • Abstract:
  • The integrity and safety of Reinforced Cement Concrete (RCC) structures decrease with time as a result of factors like material degradation, environmental effects, and variations in load conditions. This paper provides a detailed overview of retrofitting and strengthening methods used to improve the performance and prolong the life of RCC structures. The necessity for retrofitting occurs due to several factors, such as aging and degradation of the material, heightened load requirements, seismic susceptibility, changes in function, and aesthetic or safety reasons. The paper presents the main reasons for RCC structure deterioration, such as concrete degradation mechanisms such as carbonation, chloride corrosion, and alkali-silica reactions, and the corrosion of the steel reinforcement. In addition, it points out general retrofitting techniques like concrete jacketing, fiber-reinforced polymer (FRP) wrapping, external post-tensioning, and steel plate or strap strengthening. Seismic retrofitting techniques, specifically, receive special treatment as they are geared towards making older buildings more resistant to earthquakes since these were not originally designed with seismic thinking in mind. New materials like high-performance concrete (HPC), steel reinforcement, epoxy resins, shape memory alloys (SMAs), and aerogel-based solutions are also investigated for their potential in retrofitting. The paper concludes by emphasizing the need for the implementation of proper retrofitting techniques and materials to restore and improve the structural capacity, safety, and resilience of RCC infrastructure.
