Title: ITG/T1.1-99: Acceptance Criteria for Moment Frames Based on Structural Testing
Author(s): ACI Committee 93

Abstract:Note: A newer version of this document exists. This document was replaced by T1.1-01/T1.1R-01.
This document defines the minimum experimental evidence that can be deemed adequate to attempt to validate the use, in regions of high seismic risk or in structures assigned to satisfy high seismic performance or design categories, of weak beam/strong column moment frames not satisfying fully the prescriptive requirements of Chapter 21 of ACI 318-99. This document consists of both a Provisional Standard and a Commentary that is not part of the Provisional Standard. The document has been written in such a form that its various parts can be adopted directly into Sections 21.0, 21.1, and 21.2.1 of ACI 318-99 and the corresponding sections of ACI 318R-99. Among the subjects covered are requirements for: procedures that shall e used to design test modules; configurations for those modules; test methods; test reports; and determination of satisfactory performance. The Commentary describes some of the considerations of the Innovation Task Group in developing the Provisional Standard. The section numbering for the Commentary is the same as that for the Provisional Standard with numbers preceded by an "R" to distinguish them from the corresponding section numbers of the Provisional Standard. The Commentary references documentary evidence, additional to the references of Chapter 21 of ACI 318-99, that supports the Provisional Standard. Consistent with the approach of ACI 318-99 and ACI 318R-99, no comparison is made, either in the body of the Provisional Standard or its Commentary, of research results for test modules satisfying ACI 318-99 with those for modules that, although not satisfying ACI 318-99, do satisfy the Provisional Standard. Such comparisons, both experimental and analytical, are available in the reference of the Commentary.
