Design guidelines for the seismic modification of welded steel moment frame buildings
Prompted by the widespread damage to welded beam-to-column connections as a result of the 1994 Northridge earthquake, the National Institue of Standards and Technology initiated a study to determine the efficacy of various techniques for the modification of existing WSMF (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. Results indicated that the modified connections are capable of developing a minimum of 0.02 radian of plastic rotation. Design guidelines, based on the experimental results, have been written in cooperation with the American Institute of Steel Construction and are described. They contain recommendations for the proportioning and detailing of the various connection modifications.
