STRUCTURAL CONCRETE BUILDING CODE/COMMENTAF
e ACl Building Code Requirements for Structural Concrete (Code") and Commentary are presented in a sidd umn format, with Code text placed in the left column and the corresponding Commentary text aligned in the right further distinguish the Code from the Commentary, the Code has been printed in Helvetica, the same type face sparagraph is set.
INTRODUCTON
Ihe Code is intended to cover all buildings of the usual types, both large and small.Requirements more stringent han the Code provisions may be desirable for unusual construction.The Code and Commentary cannot replace soundengineeringknowledge,experience, and judgment.
A building code states only the minimum requirements necessary to provide for public health and safety. The Code is based on this principle. For any structure, the owner or the licensed design professional may require the quality of materials and construction to be higher than the minimum
For a history of the ACI Building Code see Kerekes, F, and Reid, H, B., Jr., "Fifty Years of Development in Building Code Requirements for Reinforced Concrete," ACI and Engineering Practice," ACI JoURNAL, Proceedings V. 56, No. 5, May 1960, p. 1105.
requirements necessary to protect the public as stated in the Code. However, lower standards are not permitted.
The Commentary directs attention to other documents that provide suggestions for carrying out the requirements and intent of theCode.However,those documents and the Commentary are not a part of the Code.
The Code has no legal status unless it is adopted by the government bodies having the police power to regulate building design and construction. Where the Code has not been adopted, it may serve as a reference to good practice even though it has no legal status.
Design reference materials illustrating applications of the Code requirements may be found in the following documents. The design aids listed may be obtained from the sponsoring organization

STRUCTURAL CONCRETE BUILDING CODE/COMMENTAR
1.1.1 — This Code provides minimum requirements for design and construction of structural concrete membersofanystructureerectedunderrequirements of the legally adopted general building code of which this Code forms a part. In areas without a legally adopted building code, this Code defines minimum acceptable standardsfor materials,design,and construction practice. This Code also covers the strength evaluation of existing concrete structures. For structural concrete,f: shall not be lessthan 2500psi.Nomaximumvalue offshall apply unless restricted by a specific Code provision.

COMMENTARY
Prestressed concrete is included under the definition of reinforced concrete.Provisions of the Code apply to prestressed concrete except for those that are stated to apply specifically to nonprestressed concrete.
Appendix A of Codes prior to 2002 contained provisions for an alternate method of designfor nonprestressed reinforced concrete members using service loads (without load factors) and permissible service load stresses. The Alternate Design Method was intended to give results that were slightly more conservative than designs by the Strength Design Method of the Code. The Alternate Design Method of the 1999 Code may be used inplace of applicable sections of this Code
Appendix A of the Code contains provisions for the design of regions near geometrical discontinuities, or abrupt changes in loadings.
1.1.2 —This Code supplements the general building code and shall govern in all matters pertaining to design and construction of structural concrete, except wherever this Code is in conflict with requirements in thelegallyadoptedgeneralbuildingcode
1.1.3This Code shallgovern inall matterspertaining odesign,construction,andmaterialpropertieswherever his Code is in conflict with requirements contained in otherstandardsreferencedinthisCode

Seismic Design Categories in this Code are adopted directly are used by the 2006 edition of the “International Building Construction and Safety Code.l.16 The “BOCA National Building Code" (NBC)l.17 and "Standard Building Code" (SBC)1.18 use Seismic PerformanceCategories.The 1997 requirements to seismic zones, whereas previous editions of ACI 318 related seismic design requirements to seismic risk levels. Table R1.1.9.1 correlates Seismic Design Categories to the low, moderate/intermediate, and high seismic risk terminology used in ACI 318 for several editions before the 2008 edition, and to the various methods of assigning design requirements in use in the U.S. under the various model building codes, the ASCE/SEI 7 standard, and the
STRUCTURAL CONCRETE BUILDING CODE/COMMENTAR
This Code does not govern design and construction of tanks and reservoirs.
1.2.1—Copies of design drawings, typical details, and specifications for all structural concrete construction shall bear the seal of a licensed design professional. These drawings, details, and specifications shall show:
(a) Name and date of issue of code and supplement to which design conforms;
[b) Live load and other loads used in design:
In the absence of a general building code that prescribes earthquake loads and seismic zoning, it is the intent of Committee 318 that application of provisions for seismic design be consistent with national standards or model building codes such as References 1.14. 1.15, and 1.16.
R1.1.9.2 Structures assigned to Seismic design category (SDC) A have the lowest seismic hazard and performance requirements. Provisions of Chapters 1 through 19 and Chapter 22 are considered sufficient for these structures. For structures assigned to other SDCs, the design requirements of Chapter 21 apply, as delineated in 21.1

COMIMENTARY
The Code permits model analysis to be used to supplement structural analysis and design calculations.Documentation of the model analysis should be provided with the related calculations.Model analysis should be performed by an individual having experience in this technique.
R1.3Inspection
STRUCTURAL CONCRETE BUILDING CODE/COMMENTAR
1.3.1 Concrete construction shall be inspectedas required by the legally adopted general building code.In theabsenceof such inspectionrequirements,concrete construction shall be inspected throughout the various Work stages by or under the supervision of a licensed design professional orby a qualified inspector.

performed well. Inspection is necessary to confirm that the construction is in accordance with the design drawings and project specifications. Proper performance of the structure depends on construction that accurately represents the design and meets code requirements within the tolerances allowed.Qualification of the inspectors canbe obtained from a certification program, such as the ACI Certification Program for Concrete Construction Special Inspector
R1.3.1 Inspection ofconstruction byorunderthe supervision of the licensed design professional responsible for the design should be considered because the person in charge of the design is usually the best qualified to determine if constructionis inconformancewith construction documents. When such an arrangement is not feasible,inspection of construction through other licensed design professionals or through separate inspection organizations with demonstrated capability for performing the inspection may be used.
In some jurisdictions,legislation has established registration orlicensingprocedures for personsperformingcertain inspection functions. A check should be made in the general building code or with the building official to ascertain if any such requirements exist within a specific jurisdiction.
Inspection responsibilityand thedegreeofinspection required should be set forth in the contracts between the owner,architect,engineer,contractor,andinspector. Adequate fees should be provided consistent with the work and equipment necessary to properly perform the inspection
K1.3.2 By inspection, the Code does not mean that the inspector should supervise the construction.Rather, it means that the one employed for inspection should visit the project with the frequency necessary to observe the various stages
