Mar 1, 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.

Notes/Preview . Preview. Description . 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.

The proper detailing and design of precast concrete connections are essential to the performance of a precast concrete structure. This guide provides information on design, detailing, and construction of connections between precast members in jointed systems, including moment frame and structural wall systems.

Precast concrete U-beams are used extensivet’y in the U.K. for medium-span bridge decks. The precast beams act compositely with an in situ concrete top slab. If it is necessary to incorporate a dapped end in a U-beam, considerable manufacturing and design difficulties arise because of the shape of a U-beam.
