Ductility Enhancement of Post-Northridge Connections by Multilongitudinal Voids in the Beam Web

Naimi, Sepanta; Çelikağ, Mürüde; Hedayat, Amir A. (Hindawi Publishing Corporation, 2013)

Since the earthquakes in Northridge and Kobe in 1994 and 1995, respectively, many investigations have been carried out towards improving the strength and ductility of steel beam to column pre- and post-Northridge connections. ...
Post-Northridge connection with modified beam end configuration to enhance strength and ductility

Hedayat, Amir A.; Çelikağ, Mürüde (Elsevier, 2009)

In order to enhance the strength and ductility of post-Northridge connections with beam depths varying from 450 mm to 912 mm, two parallel horizontal long voids were opened on their beams web. Results showed that the ...
Wedge Design: A Reduced Beam Web (RBW) Connection for Seismic Regions

Hedayat, Amir A.; Çelikağ, Mürüde (MULTI SCIENCE PUBL CO LTD, 2010)

After the Northridge earthquake, it became clear that welded flange-bolted web connections for deep beams do not have adequate ductility when subject to seismic loading. Previous experimental tests on two such connections ...
