Prompted by the widespread damage to welded
beam-to-column connections as a result of the 1994
Northridge earthquake, the National Institute of
Standards and Technology (NIST) initiated a study to
determine the efficacy of various techniques for the
modification of existing welded steel moment frame
connections to improve their seismic performance.
Problems associated with retrofitting of existing WSMF
buildings are discussed and the alternative strategies
selected for study are described. Results of 18
full-scale tests of two-sided (interior) connections,
some having a lightweight concrete slab on metal deck,
are presented. Design guidelines, based on the
experimental results, have been written in cooperation
with the American Institute of Steel Construction (AISC)
and are described.
