Abstract
The Northridge earthquake in 1994 awoke the engineering design community to a problem that had been, literally, “hidden” until then. Covered by fireproofing or closed behind ceilings, steel moment connections were revealed to have sustained not only severe damage during this most recent earthquake, but also gave indication that previous earthquakes had contributed to their current state of distress. The performance of the moment-frame in seismic regions has hitherto raised no concern. Observations of the behavior of experimental specimens and existing structures have reinforced the confidence placed on this structural system’s ability to resist lateral forces and sides way. An extensive survey of the California buildings, however, has exposed the fact that the simple design rules practiced since the 1950’s, are no longer satisfactory (Chen and Yamaguchi, 1996).
