Abstract
Beam connections with reduced drilled section and slotted web have been presented after
the Northridge earthquake (1994). Their new geometrical shapes have been resulted in
weakening of beams and subsequently the bette rperformance of connections in the
earthquakes. In this research, the advantages of both connections, mentioned above, have
been studied in the Slotted Web Drilled Flange (SWDF) composite connections. Accordingly,
the effects of different parameters of slot such as length, width and end hole dimension have
been assessed as well. Based on the results obtained in this research,energy dissipation is
reduced due to the increase of length of slot web in the SWDF connection, exceeded the
values recommended in the codes. Besides, the stability of hysteresis curve decreases
because of increasing in the width and end hole diameter of web slot.
