Abstract:
This is the third article from ACI Committee 562, Evaluation, Repair and Rehabilitation of Concrete Structures, discussing changes in ACI CODE-562-25. It focuses on providing background information on novel aspects currently included in Chapter 8—Reinforcement Details and Condition for Structural Evaluation and Repair Design and probable new directions for this chapter for the next edition of the Code.
