ABSTRACT

Two large-scale reinforced concrete column specimens were designed to investigate seismic performance, one for bending failure and the other for shear bond failure. Tested under low cycle reversed loading using a 40000kN loading system, the specimens' seismic behavior was analyzed in terms of failure characteristics, hysteretic behavior, deformation, and energy dissipation. Results indicate that specimen WF-4-7-.4 exhibited bending failure, demonstrating superior energy dissipation and deformation capacity with the plastic hinge region accounting for approximately 90% of total deformation. In contrast, specimen JF-2-7-.4 experienced shear bond failure, displaying narrow hysteresis curves, low energy dissipation capacity, and reduced ductility.
