Abstract:
In the most recent updates to the ACI 355 prequalification standards, changes were made to the requirements for testing and assessment of anchors intended for use in seismic design environments (SDC C through F). These changes are reflected in ACI CODE-355.2-24 and ACI CODE-355.4-24. Both standards are referenced in ACI CODE-318-25, “Building Code for Structural Concrete—Code Requirements and Commentary.” This article provides background for these changes, including a historical perspective on seismic qualification and design of anchorage, supporting research, and ACI Committee 355 decisions.
