Back to Past-Presidents’ Memo List. These Awards will celebrate innovation and adi excellence throughout the global concrete design and construction community. Consequently, our next code edition will be and every three years after that.

Little did we know what the future held. These are exciting times that require a change in our organizational approach as well as our publishing schedule.

Practicing structural engineers in the United States understand that ACI does not become a legal code until it is incorporated into a model cai code, which is normally then adopted by a local jurisdiction as its building code.

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.


In recent history, there have been three recognized model building code agencies in the United States. Where previously the ACI document was used by the three model code groups, it will now be used by only one in the IBC 138-99 Background and illustrative examples are presented to demonstrate important concepts and appropriate use.

In the preparation 31-99 IBCseveral things became apparent. 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. Many of these suggested changes are the result of our desire to address the modifications or differences that existed between and UBC.
