Hello

This is ACI318M-08 (For SI Unit)

ACI 318M-08 was adopted as a standard of the American Concrete Institute November 2007 to supersede ACI 318M-05 in accordance with theInstitute’s standardization procedure and was published July 2008.
A complete U.S. Customary unit companion to ACI 318M has been
developed, 318; therefore, no U.S. Customary unit equivalents are included
in this document.

Every 3 years, the ACI opens discussion to update the ACI-318 Standard.

Now, it's in discussion again! This post is for who wants to know what are in study to change.

PROPOSED CHANGES TO ACI 318-08 OPEN FOR PUBLIC DISCUSSION:

ACI Committee 318, Structural Concrete Building Code, has almost completed its work on the latest edition of the Code, “Building Code Requirements for Structural Concrete and Commentary (ACI 318-11).” As part of its activities at the ACI Fall Convention in Pittsburgh, PA, Committee 318 provided responses to comments from the ACI Technical Activities Committee (TAC) on the ACI 318-11 draft. TAC has since approved the responses, and in accordance with ACI’s standardization procedures, the draft is now available for public review for a 45-day period. The draft can be downloaded at . Interested parties are invited to read and provide comments using the posted comments form no later than January 17, 2011. Where renumbering of sections, tables, or equations is the only change to ACI 318-08 text, it is not listed below Some of the changes include:

- Design requirements for adhesive anchors are now included. Failure modes and corresponding nominal strengths are defined, as are requirements for testing and evaluation of adhesive anchors for use in cracked concrete or subject to sustained loads. The new provisions also include criteria for overhead adhesive anchors; seismic requirements for anchoring to concrete; installation and inspection of adhesive anchors; and certification of adhesive anchor installers. (A related draft standard, “Acceptance Criteria for Qualification of Post-Installed Adhesive Anchors in Concrete and Commentary [ACI 355.Y],” is a prerequisite for the design of adhesive anchors in concrete and is currently open for public discussion until December 17, 2010.);

- Reinforcement detailing requirements for seismic applications have been enhanced. These enhancements include rules for identifying and detailing distinct segments of a special structural wall, detailing of horizontal bars at special boundary elements, and confinement of beam flexural hinge regions;

- New test methods for sulfate resistance are included. ASTM D516 and D4130 are identified tests for sulfate ions in water, brackish water, or seawater, and ASTM C1580 is identified as a test for watersoluble sulfate in soil;

- New deformed bars are included. Grade 80 deformed bars per ASTM A615 and A706 are allowed for nonseismic applications. Zinc and epoxy dual-coated reinforcing bars per ASTM A1055 are also now allowed;

- Test records for determining standard deviation for mixture design may now be up to 24 months old. Also, testing agencies performing acceptance testing concrete are now required to comply with ASTM C1077;

- New requirements for detailing of circular column ties, design and detailing of temperature and
shrinkage reinforcement for post-tensioned slabs, and minimum reinforcement for deep beams have been added. Also, development length for headed bars has been revised; and

- Factored load combinations have been revised to conform with ASCE 7-10.

ACI 318-11

The "Building Code Requirements for Structural Concrete" ("Code") covers the materials, design, and construction of structural concrete used in buildings and where applicable in nonbuilding Structures. The Code also covers the strength evaluation of existing concrete structures. Among the subjects covered are: contract documents; inspection; materials; durability requirements; concrete quality, mixing, and placing; formwork; embedded pipes; construction joints; reinforcement details; analysis and design; strength and serviceability; flexural and axial loads; shear and torsion; development and splices of reinforcement; slab systems; walls; footings; precast concrete; composite flexural members; prestressed concrete; shells and folded plate members; strength evaluation of existing structures; provisions for seismic design; structural plain concrete; strut-and- tie modeling in Appendix A; alternative design provisions in Appendix B; alternative load and strength reduction factors in Appendix C; and anchoring to concrete in Appendix D. The quality and testing of materials used in construction are covered by reference to the appropriate ASTM standard specifications. Welding of reinforcement is covered by reference to the appropriate American Welding Society (AWS) standard. Uses of the Code include adoption by reference in general building codes, and earlier editions have been widely used in this manner. The Code is written in a format that allows such reference without change to its language. Therefore, background details or suggestions for carrying out the requirements or intent of the Code portion cannot be included.
