- # -2009 International Building Code
- # -33The 2009 IBC came out in March 2009.
It is scheduled to become effective in the State of California
Jan 1 2011.
Changes between the 2006 IBC and the 2009 IBC are shown with
black bars in the margin. An arrow indicates a deletion.
Ask how many people have the 2009 IBC; typically we get a
response that 90% have not purchased.ACI 318-11

ASCE 7-10Supplement No. 1being processed now.- # -Adoption of
ACI 318-11ACI 318-11 adopted into the 2012 IBC
sight-unseenUnderstanding was that it would be removed by errata if
it did not come out in print by a certain dateA number of other
standards was adopted by the same administrative maneuver- # -
- # -Significant changes from ACI 318-08 to ACI 318-11Rules for
deformed bar types are updated. Grade 80 deformed bars per ASTM
A615 and A706 are allowed for non-seismic applications. Zinc and
epoxy dual-coated reinforcing bars per ASTM A1055 are now
recognized.- # -Significant changes from ACI 318-08 to ACI
318-11New test methods for sulfate resistance are included. ASTM
D516 and D4130 are identified as tests for sulfate ions in water,
brackish water, or seawater, and ASTM C1580 is identified as a test
for water-soluble sulfate in soil.- # -Significant changes from ACI
318-08 to ACI 318-11Test records for determining standard deviation
for a mixture design may now be up to 24 months old. Also, testing
agencies performing acceptance testing of concrete are now required
to comply with ASTM C1077.- # -Significant changes from ACI 318-08
to ACI 318-11New 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.- # -Significant changes from ACI 318-08 to
ACI 318-11Factored load combinations have been revised to conform
to ASCE 7-10.- # -Significant changes from ACI 318-08 to ACI
318-11Reinforcement detailing requirements for seismic applications
have been enhanced. These enhancements include rules for detailing
of horizontal bars at special boundary elements of special shear
walls, and confinement of beam flexural hinge regions.- #
-Significant changes from ACI 318-08 to ACI 318-11Door and window
openings in shear walls often lead to narrow vertical wall
segments, many of which have been defined as wall piers in the IBC
and in the UBC before it. Wall pier provisions are now included in
ACI 318-11. The dimensions defining wall piers are given. Detailing
is prescribed, which would result in flexural failure preceding
shear failure in wall piers. - # -Significant changes from ACI
318-08 to ACI 318-11Design 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.-
# -Significant changes from ACI 318-08 to ACI 318-11The 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.- # -Reorganization of ACI 318-11ACI

# -Your input soughtwww.concrete.org/COMMITTEES/318Public.htmA
Submit Questions/Comments button facilitates communication with the
committee. Questions and comments will be reviewed, and the FAQ
section will be periodically updated with answers to commonly asked
questions. ACI Committee 318 may also conduct surveys to solicit
specific input and feedback from users of the Code.- # -ACI 318-14
scheduleACI 318 balloting schedule shows the last letter ballot in
January 2012. The committee will meet in the 2012 Spring Convention
in Dallas (March 18-22). The committee will probably meet in the
summer of 2012 also to resolve issues. TAC review comes next,
followed by public review.The Standard (minus the Commentary) is
expected be finalized at the Spring 2013 convention (mid April) in
Minneapolis.- # -IBC Adoption of ACI 318-14A submissions will be
prepared for the January 3, 2012 code change deadline for the 2015
IBC.The submission will assume 318-14 will be at a stage to print a
few "final" copies for ICC review by late September 2013, in which
case 318-14 will be referenced in Chapter 19 of the 2015 IBC.If
review copies cannot be printed in time, 318-11 will remain the
reference standard in the 2015 IBC. ACI 318-14 will then be adopted
by 2018 IBC.
- # -IBC Adoption of ACI 318-14The process to include 318-11 in
the 2012 IBC occurred before 318-11 was finalized. So all
exceptions and additions in IBC Chapter 19 to ACI 318 are based on
318-08. This creates some problems and inconsistencies.A second
code change is being prepared to remove these inconsistencies and
will also be submitted by the January 3, 2012 deadline.
- # -Developments since ACI Convention, Fall 2011, CincinnatiAt
the last convention, the plan was to maintain the 318-11 reference
in the 2015 IBC, because the 318 steering committee agreed that
more time was needed to finish 318-14 than was previously
available.Dan Falconer, ACI
- # -Developments since ACI Convention, Fall 2011, Cincinnati
the ICC timetable has since changed and now approximately matches
up with what the steering committee thought was needed to finish
318-14. ACI will therefore propose inclusion of 318-14, and not
318-11, in the 2015 IBC. At this time, I can't provide a revised
detailed 318 schedule, but this is the big picture.Dan Falconer,
ACI- # -Developments since ACI Convention, Fall 2011, CincinnatiI
can tell you that CP 28 was revised such that for the 2012/13 cycle
and beyond, updates to currently referenced [standards] will still
be processed via the IADMIN committee (Group B with a code change
deadline of Jan 3, 2013) and that the updated standard needs to be
available by 12/1/14. Mike Pfeiffer, ICC
- # -Developments since ACI Convention, Fall 2011, CincinnatiIn
effect, the Board has made permanent the 09/10 cycle provision for
updating standards....Mike Pfeiffer, ICC- # -Developments since ACI
Convention, Fall 2011, CincinnatiFirst, the referenced standards
revised through the administrative process need to be available for
purchase by December 1, 2014. Second, new referenced standards must
be submitted with the code change proposal. The status of such new
standards is currently defined as "an official draft," which is
somewhat unclear. Matt asked if the draft after the final committee
ballot was acceptable and Mike answered that such a draft is OK.Dan
Falconer, ACI
- # -318-14 Completion Schedule
Regarding a schedule for completion of 318-14, it takes about 2
months from completion of committee responses to public comments to
be available for purchase; therefore, the fall 2014 meeting can't
be part of the schedule. My guess is that the committee has about
30 months [until Summer 2014] to finish in order to be
referenced.Dan Falconer, ACI
