Abstract: The concrete filled tubes (CFT) have the complete utilization of strength of its components both steel and concrete due to its peculiar positioning. The presence of outer steel improves the confinement of concrete which leads to high stiffness and strength, where as core concrete will support the steel tube from local buckling and enhance the overall performance. The application of CFT is limited due to the lack of design guidelines for the joint between CFT and structural steel beams especially in seismic regions. This paper attempts to evaluate and compare the hysteretic performance of two extended end plate exterior beam column connection suitable for square and circular CFT by investigating the strength, stiffness, ductility and energy dissipation. The results indicate the adaptability of both connections for Special moment resisting structure with consistently stable, ductile and good energy dissipation nature.
