ACI 543R-12 Design, Manufacture, and Installation of Concrete Piles
Concrete piles are structural elements that are driven or cast into the ground to support foundations, bridges, buildings, and other structures. They are widely used in geotechnical engineering because they can transfer loads to deeper and more competent soil layers, resist uplift and lateral forces, and improve the stability of the soil. However, designing, manufacturing, and installing concrete piles requires careful consideration of various factors, such as the subsurface conditions, the structural loads, the pile type and size, the quality control, and the installation methods. To assist the engineers and contractors in this process, the American Concrete Institute (ACI) has published a guide titled "ACI 543R-12 Guide to Design, Manufacture, and Installation of Concrete Piles".
This guide presents recommendations for most types of concrete piles, including precast prestressed concrete piles, precast nonprestressed concrete piles, cast-in-place concrete piles, composite piles, and augered piles. It covers the geotechnical design considerations, such as the bearing capacity, the settlement, the group action, the lateral support, the axial load distribution, the long-term performance, the lateral capacity, and the uplift capacity of concrete piles. It also covers the structural design considerations, such as the loads and stresses to be resisted, the reinforcement details, the prestressing requirements, the durability requirements, and the serviceability requirements of concrete piles. Moreover, it provides guidance on the manufacture and storage of precast concrete piles, as well as the installation methods and equipment for different types of concrete piles. It also discusses the inspection and testing procedures for quality assurance and quality control of concrete piles.
The guide is intended for use by individuals who are competent to evaluate the significance and limitations of its content and recommendations. It is based on the current state of knowledge and practice in the field of concrete pile design and construction. It is not intended to replace or supersede any codes or standards that may apply to specific projects or jurisdictions. The guide is available in PDF format from [the ACI website].
