چکیده    After northridge and kobe earthquakes, several studies have been conducted to improve the seismic performance of steel structures. in this investigation, new steel moment-resisting connections (fsfn) developed by the authors were studied by the non-linear numerical analysis. these connections were single-sided beam-to-column assemblies that are representative of exterior beam-to-column connections. seismic performance of fsfn connections in comparison to the w-series of existing kbb connections under standard and near fault load history based on aisc 341 and fema 355d were also studied. for this purpose, 32 analytical modeled specimens were evaluated and the results were compared. results showed that fsfn bracket connection has a seismic performance similar to kbb connection and it is an appropriate connection for the special moment resisting frames both in far and near fault zones. more so, these brackets have smaller dimensions as compared with kaiser connections, they can support deeper beams up to 100 cm. therefore, they can be considered as an appropriate alternative for the kaiser patented connections. this paper presents the analytical modeling, non-linear behavior and the results of the comparison studies in detail including obtained conclusions. © 2013 elsevier b.v.
