Part 1 – An Overview of ACI 318-19 and the Concrete Chapter of the 2021 IBC

The 2021 IBC has been available since October 2020. It has been adopted by a few jurisdictions already and will be adopted by the state of California on January 1, 2023. Other major adoptions will follow. The 2021 IBC Chapter 19, Concrete adopts ACI 318-19, whereas ACI 318-14 was the referenced standard in the 2018 IBC.

There is a large number of technical changes from ACI 318-14 to ACI 318-19, many of which are quite substantive and some of which are of far-reaching consequences. An overview of the extensive changes will be provided in two 2½ – hour webinars. Part 1 will address changes in the concrete chapter of the 2021 IBC, ACI 318-19 Chapters 1 through 17, and the beginning parts of Chapter 18. Part 2 will discuss changes in the rest of Chapter 18, Chapters 19-27, and Appendix A.
