Abstract:
This is another in a series of articles intended to explain some of the new content in the 2016 edition of the ACI 562 Code. It discusses the updated interface bond provisions and includes an example to illustrate the application and significance of these new provisions. It also provides excerpts from the new guide to the ACI 562-16 Code produced in a collaboration between ACI and the International Concrete Repair Institute.
