Experimental Study on Aseismic Performances of Dampers in forms of Concrete Ductile Columns

In order to study the main effected factors of the aseismic performance of concrete dampers,experiment of dampers in forms of concrete ductile columns was conducted subjected to low cyclic loading,The damage pattern,hysteresis behavior,ductility factor and equivalent viscous damper factor of the dampers were obtained.The analysis showed that the hampers of ductle column possessed good aseismic performance.
