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 ...

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.

533R-11(21) Guide for Precast Concrete Wall Panels . 533.1R-20 Guide for Design and Construction Responsibilities for Architectural Precast Concrete . 533.5R-20 Guide for Precast Concrete Tunnel Segments . 543R-12 Guide to Design, Manufacture, and Installation of Concrete Piles . 544.1R-96(09) Report on Fiber Reinforced Concrete

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.

For provisions that specifically address precast concrete and are generally not within the scope of post-tensioning, this code references either ACI CODE-318 or ACI-PTI CODE-319, where applicable. Much of the research data referenced in preparing the Code is cited for the user desiring to study individual questions in greater detail.

This Reference Specification provides standard tolerances for precast concrete construction. It covers dimensional tolerances for precast concrete members used in building construction, and it covers erection tolerances for these members. This document is intended to be adopted by reference in Contract Documents.
