Apr 2, 2025 · The American Concrete Institute (ACI), in collaboration with the Precast/Prestressed Concrete Institute (PCI), is pleased to announce the release of ACI/PCI CODE-319-25: Structural Precast Concrete—Code Requirements and Commentary in PDF format. This highly anticipated code provides essential guidance for the materials, design, and detailing ...

Design of precast, post-tensioned concrete structures requires the use of applicable provisions of ACI CODE-318, ACI/PCI CODE-319, and ACI/PTI CODE-320. For provisions that specifically address post-tensioning and are generally not within the scope of precast concrete, this code references either ACI CODE-318 or ACI/PTI CODE-320, as applicable.

Notes/Preview . Printed copies of this document will be available in early July 2025. Description . The “Building Code for Structural Concrete” (“Code”) provides minimum requirements for the materials, design, and detailing of structural concrete …

Apr 25, 2025 · Definition: concrete cast elsewhere than its final position.- ACI Concrete Terminology. Precast concrete is reinforced concrete constructed by industrialized methods. It is characterized by dividing the building into components, which are manufactured in a precast concrete plant, and transported by special transportation equipment to the site.

The American Concrete Institute (ACI) is a leading authority and resource worldwide for the development and distribution of consensus-based standards, technical resources, educational programs, certification programs, and proven expertise for individuals and organizations involved in concrete design, construction, and materials, who share a commitment to pursuing the best …

This guide presents recommendations for precast concrete wall panels. It should be used with ACI 318-08, “Building Code Requirements for Structural Reinforced Concrete,” which is legally binding when adopted by the local authority.

Sep 1, 1998 · The analytically simulated performance of moment-resisting precast concrete frames with hybrid connections under seismic loads is evaluated. An enhanced and versatile hysteretic model was developed to represent the inelastic behavior of the hybrid precast connection region.
