- Abstract
- After a brief overview of the building seismic design, nonlinear response spectra for strength, ductility, energy and number of yield reversals as a function of building period and structure strength for several strong motion earthquakes are presented. These results are compared with conventionally evaluated elastic response spectra and code criteria. The basic reasons for the fractures that occurred in steel moment-resisting connections during the 1994 Northridge earthquake are examined. The possible modes of failure are examined, showing the very limited view in the code design. Three SAC pre-Northridge specimen tests subjected to cyclic loading are critically examined.
