Residential Code Requirements for Structural Concrete (ACI 332M-10) and Commentary
|Publication Date:||1 August 2010|
This Code, when legally adopted as part of a general building code, provides minimum requirements for design and construction of residential concrete elements. In areas without a legally adopted building code, this Code defines minimum acceptable standards of design and construction practice.
The user of this Code should consult the applicable general building code for all applied loads to determine the applicable values for design requirements. In the absence of a governing code, the user should consider the use of ASCE/ SEI 7 to determine applicable loads.
This Code supplements the general building code and governs matters pertaining to design and construction of cast-in-place concrete construction for one- and two-family dwellings and multiple single-family dwellings (townhouses), and their accessory structures, except wherever this Code conflicts with requirements in the legally adopted general building code.
Where this Code conflicts with requirements contained in other standards referenced in this Code, this Code shall govern.
The IRC references this Code. Where the design of an element is initiated with this Code from reference by the IRC, the entire design of the element must be completed using the provisions of this Code
This Code is limited to design and construction of concrete footings, including thickened slab footings, wall footings, and isolated footings; concrete basement or foundation walls constructed with removable forms or with flat insulating concrete forms; and concrete slabs-on-ground.
The design and construction requirements for footings, foundation walls, and slabs-on-ground are included in this Code, together with requirements for concrete, reinforcement, forms, and other related materials.
Where the scope of this Code and the scope of ACI 318M coincide, design in accordance with ACI 318M shall be permitted for all buildings and structures, and all parts thereof, within the scope of this Code.
This Code does not govern design and construction of insulating concrete form walls with a waffle or screen configuration; precast wall elements; above-grade concrete walls; deep foundation systems, such as piles, drilled piers, or caissons; and elevated concrete slabs.
Provisions for application of precast wall elements are found in the International Residential Code (IRC) and other publications. The provisions for above-grade concrete walls are currently available in the 2009 IRC based on the PCA 100 Standard or directly found in the PCA 100 Standard.
This Code does not govern the design and application of systems for surface drainage, waterproofing, dampproofing, and the ventilation of radon gases.
Guidance on the type and application of systems for drainage, waterproofing, dampproofing, and radon gas ventilation are commonly found in the general building code.
When a building or structure contains elements that exceed the limits of this Code or otherwise do not conform to this Code, these elements shall be designed in accordance with ACI 318M.
Where permitted by the statutes of the jurisdiction where the project is to be constructed, construction documents for residences designed by the provisions of this Code need not be prepared by a Licensed Design Professional. Where required by the statutes of the jurisdiction where the project is to be constructed, a Licensed Design Professional shall prepare the construction documents for residences.
The Code is intended to state only minimum requirements necessary to provide for public health and safety for the design of residences that fall within the scope of the International Residential Code (IRC). The owner or the Licensed Design Professional may require the quality of materials and construction to be higher than the minimum requirements stated in the Code.
The Code is not intended to define contractual responsibilities between all the parties involved in a project, nor is the Code intended to settle disputes regarding contractual responsibilities.
The commentary text, tables, figures, or illustrations shall not be used to interpret the Code in a way that conflicts with the plain meaning of the Code text, or to create ambiguity within the Code that would not otherwise exist.
The English version in U.S. customary units is the official version of the Code. In case of conflict between the official version and versions with SI units or in different languages, the official version governs.
