Inspection of Concrete Elements Reinforced or Strengthened with Fiber-Reinforced Polymers

Fiber Reinforced Polymers (FRPs) offer higher durability and better performance than steel in strengthening and repairing existing structures, as externally bonded systems and as internal reinforcement for concrete elements, and can increase the life cycle of concrete elements. Nevertheless, FRP reinforced/strengthened concrete (FRP-RSC) elements need to be inspected regularly for effective maintenance and to ensure safety.

This book addresses the absence of inspection guide and procedures. It reviews serviceability considerations along with specification and standards for design and installation. It identifies potential damage and anomalies attributed to FRP-RSC elements, and evaluates inspection methods. It proposes solutions for improving the detectability of FRP defects such as non-destructive testing methods. It offers a guide for in-service inspection of FRP-RSC elements, condition rating tables, examples, and guidance for load rating.
