摘　　要：通过对未安装阻尼器的纯框架结构和按不同的承载力分配率层层设置阻尼器的结构进行非线性地震反应分析,考察不同的承载力分配率条件下软钢阻尼器的减震效果。通过参数分析得到验证,存在使阻尼器的减震效果达到最佳状态的受剪承载力分配率,其值大约为0.4～0.6,同时也表明在较大的分配率范围内阻尼器均具有明显的减震效果。In this paper, the nonlinear seismic response analysis is done on the frame without damper and the frame attached dampers floor by floor according to different shear strength ratio in order to discuss the seismic mitigation effect of hysteretic dampers. It is proved by parameters analysis that there is an optimum shear strength ratio and it makes the mitigation effect of dampers achieve the optimum. Its value is about 0.4 - 0.6. Meanwhile, the hysteretic dampers have significant seismic response mitigation effect when this ratio changing in a relatively wide range.
