摘　　要：提出了一种新型单向阻尼器,其主要工作元件为油液、单向阀以及弹性元件。该阻尼器的受力特点是:无论阻尼器的位移或速度处于何种相位,阻尼力始终为拉力。使用ETABS建立了三个简化高层建筑结构多质点模型,进行了设防烈度下地震时程分析,提取出自振周期、位移、加速度以及内力结果进行对比,分析了单向阻尼器对于某高层建筑结构模型的抗震性能影响。An innovation type of damper is put forward, which is called one-way damper. The main parts of the damper are oil, one-way valve and elastic component. The characteristic of one-way damper is：the damping force is always kept in tension wherever the displacements or velocities are. Three simplified multi-mass-point models were established by ETABS and the seismic time history analysis was executed. The results-natural periods of vibration, displacements, accelerations and internal forces were compared. The influence of one-way damper on seismic resistant behavior of a high-rise building was analyzed as well.
