Abstract:

Note: 408.3-01/408.3R-01 is available in PDF format only. However, a newer version of this document exists. This document was replaced by 408.3R-09.

This standard was created to help designers take advantage of the improved bond characteristics of high relative rib area deformed reinforcement. This type of reinforcement can be produced by increasing rib height, decreasing rib spacing, or employing a combination of the two. This standard is intended to be a more efficient means of providing a development and splice length expression for the high relative rib area bars than altering the current ACI 318-99 Chapter 12 provisions to accommodate bars that are not yet in commercial production.
