Abstract

Two kinds of post-Northridge proposed beam-to-column connections are End Plate 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 connection substructures in ANSYS, ver.10. 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 approximately equal total energy dissipation. Finally, analytical inspection on the mentioned parameter represented that, due to behavior sensitivity and failure mode variation probability for bolted T-stub connection under cyclic load, despite having higher moment resistance capacity, it is recommended to design bolted End Plate connection in cases where weak construction is probable.
