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.

The proposed revisions to to be incorporated in are included at the end of this issue of Concrete International. Many of these suggested changes are the result of our desire to address the modifications or differences that existed between and UBC.
1. ACI 318 99
The moment capacity of wall cross sections is based on a strain compatibility analysis, and two vode are provided to determine whether specially detailed boundary elements are required. To aid in cpde transition to the edition of ACIseveral resources are available in the online Portal. The quality and testing of materials used in construction are covered by reference to the appropriate ASTM standard specifications.
Please contact member services for pricing. ACI University is a global, online learning resource, providing on-demand access to a wide range of topics on concrete materials, design, and construction.
The first approach can be applied to all wall sections and involves checking a 0. The primary purpose for publishing this manual is to assist the enginer and architect in the proper application of the design standars.
In the future we will endeavor to produce a code that will always precede the IBC code by a year.
Wallace and Kutay Orakcal Publication: 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. However, a newer acl of this document exists.
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. 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.
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 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.
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 coe.

These are exciting times that require a change in our organizational approach as well as our publishing schedule. Background and illustrative examples are presented to demonstrate important concepts and appropriate use.
A newer version of this document exists. Where previously the ACI document was used by the three model code groups, it will now be used by only one in the IBC 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.
ACI Provisions for Seismic Design of Structural Walls
This document was replaced by EB Back to Past-Presidents’ Memo List. The ACI provisions apply xode both slender and stout walls, and walls with openings.
The text and design examples have been revised to reflect, where possible, core received from users of the “notes” who suggested improvements 318-999 wording, identified errors, and recommended items for inclusion or deletion. All of the members of the committee understood that we would publish an interim code in and a major new one in We on Committee undertook the task of minimizing those differences between IBC and the new version of ACI that would be referenced.
All of you have the right to comment on these proposed revisions until February 1, The International Codee 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.
This will demand a change in our approach to revisions since we have been publishing a new code every six years since Among the subjects covered are: The emphasis is placed on “how to use” the code.

Although the stress limit is the same as that in ACIsignificant changes were incorporated to address commonly identified shortcomings associated with the ACI provisions. 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.
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:. Because the ACI Building Code is written as a legal document so that it may be adopted by reference in a general building code, it cannot present background details or suggestions for carrying out its requirements or itent.
Other documents that provide suggestions for carrying out the requirements of the code are also cited. Second, the plus differences that had existed in UBC would be carried forward to IBC as plus modifications to
