Abstract:
In August 2024, ACI published ACI PRC-ITG-11-24: Statistical Techniques for Assessment of Existing Concrete Structures—Report. This document, prepared by Innovation Task Group 11, which was created by the ACI Technical Activities Committee, provides information on using statistical techniques to evaluate condition and reliability of concrete structures and assessing possible repair options.
