Full Name

ICC-ES AC468 – Acceptance Criteria for Alternative Seismic Design of Precast Concrete Diaphragms and Qualification of Precast Concrete Diaphragm Connectors

Scope

ICC-ES AC468 establishes the acceptance criteria for alternative seismic design of precast concrete diaphragms and the qualification of precast concrete diaphragm connectors.

The scope of AC468 includes:

  • Alternative seismic design: this criteria provides guidelines for designing precast concrete diaphragms using alternative methods that may differ from traditional prescriptive approaches. These alternative methods can offer greater flexibility and efficiency in design while ensuring adequate seismic performance.
  • Diaphragm connectors: the criteria also outlines the requirements for qualifying precast concrete diaphragm connectors. These connectors are crucial for ensuring the integrity and continuity of the diaphragm during seismic events, transferring forces between precast elements effectively.
