Analytical Assessment and Comparison of Cyclic Behavior of End Plate and T-stub Bolted Connections Due to Horizontal Arrangement Variation of Column Bolts

Two kinds of Post-Northridge proposed beam-to-column connections are End palte and T-stub bolted connections. The aim of this paper is assessment and comparison of cyclic behavior of the mentioned connections due to horizontal variation of column bolts from centerline of beam web by finite element modeling of eight mentioned connections substructures in ANSYS, verlO. The results show that, if the mentioned connections are designed for equal sections of beam and column according to the AISC code, T-stub connection will have more moment resistance capacity and elastic stiffness than End plate connection while they have equal total energy dissipation approximately. Finally, analytical inspection on the mentioned parameter represented, attention to the behavior sensitivity and failure mode variation probability for bolted T-stub connection under cyclic load due to this partameter variation,despite T-stub connection has more moment resistance capacity, it is recommended to design bolted End plate connection rather than T-stub connection in cases that a weak construction is probable.
