Suite of Codes

ACI offers a suite of concrete knowledge with a wide range of individual codes available via print or digital download and can be found online in the ACI store.

The American Concrete Institute (ACI) offers dozens of codes that help design professionals create quality concrete projects around the world.

Covering topics such as structural concrete design; concrete repair; precast concrete; seismic anaylsis; residential concrete and more, ACI codes are developed through a consensus process that has produced dependable standards for over 100 years.

Individual codes are available via print or digital download from the ACI store. You can also access all ACI codes and standards through the ACI Collection Online Subscription.

ACI Codes are developed by volunteer committees made up of the brightest minds in concrete. Twice a year, hundreds of ACI committees convene at the ACI Concrete Convention to develop documents necessary to keep up with the ever-changing world of concrete technology.

To get involved in the Institute’s document development process, you can apply and join more than 3,000 other volunteers serving on committees.

Seismic Evaluation and Retrofit of Existing Concrete Buildings-Code and Commentary

Document Details

This code provides retrofit and rehabilitation criteria for reinforced concrete buildings based on results from the most recent research on the seismic performance of existing concrete buildings. The intent of this code is to provide provisions related to concrete material and concrete members, including material testing criteria, modeling parameters, and acceptance criteria for use within the ASCE 41 framework, similar to how the National Earthquake Hazards Reduction Program (NEHRP) Recommended Seismic Provisions produced by the Federal Emergency Management Agency (FEMA) (FEMA 450) have served as source documents for the International Building Code (IBC) and its predecessor building codes. Starting in the 2023 edition, ASCE 41 references ACI 369.1 directly for concrete-related provisions. Chapter and section numbers of ASCE 41 cited in ACI 369.1 correspond to ASCE 41-17 unless otherwise noted.
