Abstract:
This paper is based on a presentation in honor of Dov Kaminetzky’s long-term interest in how to use reinforcement location techniques in evaluating concrete structures. All methods of locating reinforcement are spot specific and can be used to determine the location of a particular reinforcement. In most cases, the engineer or contractor needs to confidently determine the location of the entire reinforcement system used in a member. This requires a detailed sampling plan to be developed and to use appropriate statistical methods. This paper describes four different reasons why reinforcement may need to be located within a structure and present a statistical method that is appropriate for each of these methods.
