Analysis on Seismic Behavior of Open Joining Column Base

In order to increase the reliability of bare column-base design in the geological process,this paper carried out numerical simulation by ANSYS on the seismic behavior of bare column-base connections and analyzed the hysteresis performance and ductility under reciprocating loads.The results showed that the open column base possessed comparatively higher yield load and ultimate bearing capacity and favourable energy-consumption property,and when the column was subjected to greater shear load with not high antiseismic demands,it was beneficial to take this form of column base.
