Abstract

The first edition of the American Concrete Institute Building Code was published in 1910. Since that time the ACI Building Code has been reviewed and revised periodically in order to keep pace with the latest research on reinforced concrete, and to remain relevant to evolving structural design and construction practices.  In the recent past, between 2008 and 2014, the organization of the ACI 318 Building Code was completely revised so that the code is easier for engineers to use in daily practice.  The current edition of the ACI Code was published in 2019: ACI 318-19/ACI 318-19R: Building Code Requirements for Structural Concrete and Commentary.  This presentation covers key modifications that were made leading up to ACI 318-19, particularly with regard to seismic design of buildings.  Finally, we examine the current direction of the ACI 318 development process, and trends to be expected in the next edition of the Code, ACI 318-25.

Biography

Andrew W. Taylor, PhD, SE, FACI, is Technical Director with KPFF Consulting Engineers in Seattle, Washington.  He is KPFF’s lead for design of special seismic systems such as seismic isolation and seismic damping.  He is also a specialist in seismic design of reinforced concrete structures.  His professional experience spans 38 years of structural engineering research and practice, including seven years with the Building and Fire Research Laboratory at the National Institute of Standards and Technology.  Dr. Taylor is a current and past member of numerous technical committees at the local and national level.  He is currently Chair of the American Concrete Institute 318 Building Code committee, which will complete the next edition of the U.S. national concrete building code in 2025.  Other memberships include the 2022 edition of the ASCE 7 building code; past project team member for Applied Technology Council project ATC-98 on the use of high-strength reinforcement for seismic design; and past Chair of the Earthquake Engineering Committee of the Structural Engineers Association of Washington.  Dr. Taylor serves as an Affiliate Professor in the Department of Civil and Environmental Engineering at the University of Washington, where he has enjoyed teaching courses in structural analysis and reinforced concrete design.
