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 …

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.

ACI 533R-11 Guide to Precast Concrete Walls and Panels Author: ACI Committee 533 Subject: 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.

The response of precast concrete diaphragms under earthquake motions depends primarily on the strength, stiffness, and deformation capacities of the connectors and the reinforcement at joints between the precast concrete members. Author: Joint ACI-ASCE Committee 550 . Publication Year: 2018 . Pages: 24 . Categories: Codes, Precast Concrete

address precast concrete detailed by emulation of cast-in-place concrete design. Performance of joints and related details of emulative precast concrete structural concepts has been extensively tested in Japan. Because emulative precast concrete structures have been constructed there for over three decades, emulative methods for seismic design are

2022年1月1日 · The performance of the precast connections was compared with previous research on similar CIP and precast specimens with GGSS placed in the footing directly at the column-footing interface. Improved seismic response was observed when the GGSS were recessed inside the footing with a debonded reinforcing bar zone inside the footing.

Early designers used precast concrete for reasons of safety, economy, and savings in time of construction. Descriptions of projects built before 1920 which used precast concrete untis weighing up to 75 tons are given. Development of the use of precast concrete for bridges, buildings, and marine construction is described.
