The American Concrete Institute (ACI), in collaboration with the Post-Tensioning Institute (PTI), announced the joint release of ACI/PTI CODE-320-25: Post-Tensioned structural concrete — code requirements and commentary in PDF format.

This new code provides minimum requirements and guidance for the materials, design and detailing of post-tensioned concrete buildings and, when applicable, nonbuilding structures.

ACI/PTI CODE-320-25 was developed through a consensus process and outlines minimum requirements for post-tensioned structural concrete systems, including members with bonded and unbonded tendons. The PTI technical advisory board code task group played a key role in developing the provisions and commentary, and ACI acknowledges their expertise and dedication.

While the code was initially made available to ACI 320 PLUS subscribers, the release of the PDF edition now makes the document more widely accessible before the upcoming printed version.

The ACI PLUS platform continues to evolve, giving industry professionals digital access to several essential codes. In addition to ACI 320 PLUS, available subscriptions include ACI 318 PLUS, ACI 319 PLUS, ACI 323 PLUS, and the ACI 562 PLUS repair subscription — all offering interactive features such as 3D graphics, advanced search tools, in-document cross-referencing and multi-set digital notetaking.

ACI/PTI CODE-320-25 is now available in PDF format through the ACI store.
