The ACI 318 Building Code Requirements for Structural Concrete and Commentary, updated for 2005
ACI 318-05 Building Code Requirements for Structural Concrete and Commentary, 2005 discusses the considerations of Committee 318 developing the provisions contained in “Building Code Requirements for Structural Concrete (ACI 318-05),” hereinafter called the code or the 2005 code.
This commentary places an emphasis on the description of revised or new provisions that could be unaccustomed to code users. Comments have also been included for different items that are seen in previous editions of the code, serving to make this commentary independent of the previous editions. Comments on specific provisions are made under the specific section numbers and chapters of the code.The commentary also sheds light on other documents that are relevant to provide suggestions for carrying out the requirements and intent of the codes.
The code presented throughout this commentary provides a means of establishing minimum standards for acceptance of construction and designs by legally appointed building officials and their designated representatives. The Code gives coverage to all buildings of the usual types, both small and large, as well as going through the minimum requirements necessary to provide for public health and safety. This text is not intended to replace sound engineering knowledge, judgment and engineering. Subsequently, for any structure, the owner or the structural designer may require the quality of materials and construction to be higher than the minimum requirements necessary in order to protect the public as stated throughout the code.
This commentary is not intended to give a complete historical background of the development of the ACI Building Code, nor is it intended to give a detailed résumé of the research and study data reviewed by the committee in coming to the provisions of the code. However, references to some of the research data are given for those who wish to study the background material in depth. As the name of the commentary implies, “Building Code Requirements for Structural Concrete” is meant to be used with the legally adopted building code and as such must differ in form and substance from documents that provide detailed specifications, complete design procedures, recommended practice or design aids.
It is recommended that users have testing and certification programs for the individual parties involved with the execution of all work performed in accordance with this code. The plant certification programs are available for this purpose of the Precast/Prestressed Concrete Institute, the Post-Tensioning Institute and the National Ready Mixed Concrete Association; the personnel certification programs of the American Concrete Institute and the Post-Tensioning Institute; and the Concrete Reinforcing Steel Institute’s Voluntary Certification Program for Fusion-Bonded Epoxy Coating Applicator Plants. In addition, “Standard Specification for Agencies Engaged in the Testing and/or Inspection of Materials Used in Construction” (ASTM E 329-03) specifies performance requirements for inspection and testing agencies. 430 pp.
