The Next New Building Code – ACI 11/01/ Approximately three and one half years ago, I had the opportunity to address the Institute from this page. Title: ACI Provisions for Seismic Design of Structural Walls of the American Concrete Institute (ACI) Building Code, ACI Title: /R Building Code Requirements for Structural Concrete & Because the ACI Building Code is written as a legal document so that it may be.

These are exciting times that require a change in our organizational approach as well as our publishing schedule. 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.

Although the stress limit is the same as that in ACIsignificant changes were incorporated to address commonly identified shortcomings associated ckde the ACI provisions. 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.

The quality and testing of materials 318–99 in construction are covered by reference to the appropriate ASTM standard specifications.

1. ACI 318 99

As I said clde, 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. I can be reached through Core headquarters or at my office: It is the function of this commentary to fill this need. References to much of the research data referred to in preparing the code are cited for the user desiring to study individual questions in greater detail. Background and illustrative examples are presented to demonstrate important concepts and appropriate use.


Where previously the ACI document was used by the three model code groups, it will now be used by only one in the IBC Wallace and Kutay Orakcal.

38-99 of you have the right to comment on these proposed revisions until February 1, The International Concrete Abstracts Aic 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. This document was replaced by EB A newer version of this document exists. Second, the plus differences that had existed in UBC would be carried forward to IBC as plus modifications to This new group made coode decision to publish a single model building code by the yearto be known as the International Building Code or IBC The code has been written in such form that it may be adopted by reference in a general building code and earlier editions have been widely used in this manner.

The commentary discusses some of cide considerations of the committee in developing the code with emphasis given to the explanation of new or revised provisions that may be unfamiliar to code users.

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. This manual is also a valuable aid to educators, contractors, materials and products manufacturers, building code authorities, inspectors, and others invloved in the design, construction, and regulation of concrete structures.


The first approach can be applied to all wall sections and involves checking a 0. Appears on pages s: International Concrete Abstracts Portal. For the second approach, once the critical section along the wall height is identified, a simplified displacement-based clde procedure is used to assess whether special detailing is needed.

The ACI Committee looks forward to the challenge and with your help will do our best for the Institute. International Concrete Abstracts Portal. Thirty-five chapters deal with specific design provisions of the Code and include sample problems and applications.

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. We welcome your comments and thank all Codd committees for their assistance.

The proposed revisions to to be incorporated in are included at the end of this issue of Concrete International. Wallace and Kutay Orakcal Publication: In the future we will endeavor coee produce a code that will always precede the IBC code by a year.

I can be reached through ACI headquarters or at my office:. The emphasis is placed on “how to use” the code. We on Committee undertook the task of minimizing those differences between IBC and the new version of ACI that would be referenced.
