“…Prior research looked into deflection, ductility, strength, energy dissipation response, reinforcement detailed requirements, stiffness, and drift reversals. Many scholars [11][12][13][14][15][16] have carried out combined experimental and numerical investigations on the performance of BCCs. [17] described a numerical evaluation of the seismic behaviour of shear deficient BCC.…”

An experimental investigation studied performance of Scorner beam-column connection (BCC) under cyclic loading. Each BCC consisted of upper, lower column and two beams; one of them was free end (A) while the other was fixed end (B). The cyclic loading was applied on the end of beam (A) while the beam (B) was unloaded and subjected to torsion stresses due to fixation. Two variables were investigated. The first is the eccentricity of the beam about column edge while the second is the effect of stirrup joint configuration on BCC under cyclic loading. All BCCs were tested under reversible fourteen cycles. The vertical displacement at the free end of the beam (A), horizontal sway at mid height of the column, crack and ultimate loads were observed in details at each cycle. The findings noticed that the increase of stirrup length in the connection decreased the deflection at the same level of the load. The ultimate load of specimen, which was shifted by 25mm, was less than the ultimate load of specimen, without shift, by 24%.When the joint stirrup was extended outside the column core by 50 mm in specimen Sp2, the capacity of the connection increased.
