摘　　要：为考察混凝土延性柱耗能器抗震性能的主要影响因素,通过对多根延性柱耗能器的低周反复荷载试验,得到其破坏形态、滞回特性、延性系数、等效黏滞阻尼系数等参数．分析表明,这些延性柱耗能器具有良好的消耗地震能量的能力．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.
