This document provides practicing engineers and building officials with a resource document
for understanding the behavior of steel moment-frame buildings in earthquakes. It is one of the
set of six State of the Art Reports containing detailed derivations and explanations of the basis
for the design and evaluation mendations prepared by the SAC Joint Venture. The
mendations and state of the art reports, developed by practicing engineers and researchers,
are based on professional judgment and experience and supported by a large program of
laboratory, field, and analytical research. No warranty is offered with regard to the
mendations contained herein, by the Federal Emergency Management Agency, the
SAC Joint Venture, the individual joint venture partners, or the partner’s directors,
members or employees. anizations and their employees do not assume any legal
liability or responsibility for the accuracy, completeness, or usefulness of any of the
information, products or processes included in this publication. The reader is cautioned to
review carefully the material presented herein and exercise independent judgment as to its
suitability for application to specific engineering projects. This publication has been
prepared by the SAC Joint Venture with funding provided by the Federal Emergency
Management Agency, under contract number EMW-95-C-4770.
Cover Art. The beam-column connection assembly shown on the cover depicts the standard
detailing used in welded, steel moment-frame construction, prior to the 1994 Northridge
earthquake. This connection detail was routinely specified by designers in the period 1970-1994
and was prescribed by the Uniform Building Code for seismic applications during the period
1985-1994. It is no longer considered to be an acceptable design for seismic applications.
Following the Northridge earthquake, it was discovered that many of these beam-column
connections had experie
