PART 3 - An Overview of Significant Changes in ACI 318-25
September 23, 2025
2:00 PM to 4:30 PM Eastern Time
1:00 PM to 3:30 PM Central Time
11:00 AM to 1:30 PM Pacific Time
S. K. Ghosh, Ph.D.
The latest edition of ACI 318 Building Code Requirements for Structural Concrete was released at the end of January, 2025. It is expected to be adopted by the 2027 IBC. ACI 318-25 introduces significant updates, including a new sustainability appendix and a new appendix on performance-based wind design, revised requirements for post-installed reinforcing bars, and enhanced provisions for shear friction.
Why Attend Part 3?
Part 3 of our webinar series will cover Chapters 19 onward of ACI 318-25, which contain some of the most impactful changes in the new Code. Attendance at Part 1 or Part 2 is NOT a prerequisite — Part 3 is a stand-alone session.
Key highlights include:
- Mechanical splice requirements – Type 1/Type 2 replaced with Classes L, G, and S
- Hooked and headed bar development lengths – revised provisions and equations
- Reinforcement requirements – ASTM A615 no longer permitted as longitudinal reinforcement in special seismic systems (SDCs C, D, E, or, F)
- Strength reduction factors – new criteria for members under combined moment and axial compression
IMPORTANT NOTE: Attendees who registered for Part 1 and Part 2, need not register for Part 3 of the series. They will be automatically registered for Part 3 of the webinar.
If you did not attend PART 1 and PART 2, but are interested in registering for PART 3, you may do so using the ADD TO CART button above.
Stay ahead of the curve and understand not just what changed in ACI 318-25, but why—and how it will impact your designs moving forward.
Speaker Bio
Dr. S. K. Ghosh is known internationally for his work in earthquake engineering. He has influenced seismic design provisions in the United States for many years by serving on or chairing numerous committees and advisory panels. He specializes in the analysis and design, including wind and earthquake resistant design, of reinforced and prestressed concrete structures. Dr. Ghosh is active on many national technical committees and is a fellow of ASCE, SEI, ACI, and PCI. He is a member of ACI Committee 318, Standard Building Code, and the ASCE 7 Standard Committee (Minimum Design Loads for Buildings and Other Structures). He is a former member of the Boards of Direction of the Building Seismic Safety Council (BSSC), the American Concrete Institute (ACI), and the Earthquake Engineering Research Institute (EERI). In addition to authoring many publications in the area of structural design, he has investigated and reported on structural performance in recent earthquakes.
