We on Committee undertook the task of minimizing those differences between IBC and the new version of ACI that would be referenced.

Each is used in different geographical areas of the U. Click here to become an online Journal subscriber. Second, the plus differences that had existed in UBC would be carried forward to IBC as plus modifications to The proposed revisions to to be incorporated in are included at the end of this issue of Concrete International.

These Awards 3318-99 celebrate innovation and inspire excellence throughout the global concrete design and construction 31-99. Where previously the ACI document was used by the three model code groups, it will now be used by only one in the IBC This new group made a decision to publish a single model building code by the yearto be known as the International Building Code or IBC Background and illustrative examples are presented to demonstrate important concepts and appropriate use.

For the second approach, once the critical section along the wall height is identified, a simplified displacement-based design procedure is used to assess whether special detailing is needed. These are exciting times that require a change in our organizational approach as well as our publishing schedule. New provisions for evaluating flexural strength and detailing requirements at boundaries of reinforced concrete structural walls were incorporated into the version of the American Concrete Institute ACI Building Code, ACI How we got there is the basis of this memo.

The Next New Building Code – ACI

As I said previously, the Building Code is a reflection of the state-of-the-art in concrete construction, as determined by the work of all of you through the technical committees of the Institute.

For this, we still have another hearing to go through in March but, assuming the version of ACI is accepted to be the referenced document xci the design of concrete structures, the number of modifications will be close to ten instead of the 60 plus which existed in UBC.

Many of these suggested changes are the result of our desire to address the modifications or differences that existed between and UBC. The moment capacity of wall cross sections is based on a strain compatibility analysis, and two approaches are provided to determine whether specially detailed boundary elements are required.

In the future we will endeavor to produce a code that will always precede the IBC ack by a year. Practicing structural engineers in the United States understand that ACI does not become a legal code until it is incorporated into a model building code, which is normally then adopted by a local jurisdiction as its building code.

The ACI Committee looks forward to the challenge and with your help will do our best for the Institute. I can be reached through ACI headquarters or at my office:. Wallace acl Kutay Orakcal Publication: Shortly after our committee started work inthe three model code groups came together and formed a new body, known as the International Code Council ICC.

I can be reached through ACI headquarters or at my office: All of the members of the committee understood that we would publish an interim code in and a major new one in This will demand a change in our approach to revisions since we have 31-899 publishing a new code every six years since We welcome your comments and thank all ACI committees for their assistance.

The International Concrete Abstracts Portal is an ACI led collaboration with leading technical organizations from within the international concrete industry and offers the most comprehensive collection of published concrete abstracts.

The ACI provisions apply to both slender and stout walls, and walls with openings. In recent history, there have been three recognized model building code agencies in the United States. The first approach can be applied to all wall sections and involves checking a 0.

In the preparation of IBCseveral things became apparent.

Although the stress limit is the same as that in ACIsignificant changes were incorporated to address commonly identified shortcomings associated with the ACI provisions. Since it is the intention of ICC to publish a building code every three years starting in the yearACI will attempt to publish in,and so on. Consequently, our next code edition will be and every three years after that.

To aid in your transition to the edition of ACIseveral resources are available in the online Portal. ACI University is a global, online learning resource, providing on-demand access to a wide range of topics on concrete materials, design, and construction.

Remember, the version of ACI that is incorporated by reference in IBC is the legally adopted code that will be used by most municipalities as their building code. Little did we know what the future held. All of you have the right to comment on these proposed revisions until February 1,
