摘要

在建立非线形粘滞阻尼器消能结构性能曲线的基础上,建议了依据减震性能目标确定阻尼器参数的概略设计方法。提出了多自由度非线性粘滞阻尼器消能结构的等效阻尼比计算公式。在此基础上建议了适用于多自由度非线性粘滞阻尼器消能结构地震反应预测的模态叠加法,方法与时程分析结果对比吻合良好。为使各层阻尼器参数更好地满足减震性能要求,提出了将概略设计得到的层阻尼器参数依据减振性能目标进行调整的方法。
Based on the performance curve,the general design method for energy dissipation structures with non-linear viscous dampers has been suggested to satisfy the performance requirement of the vibration mitigation target.The equivalent damping ratio expression of multi-degree energy dissipation structures with non-linear viscous dampers has been presented.The mode superposition method is applied to analyze the seismic response of the structures.Comparison of the numerical results of the present method with the step-by-step time history method show reasonable of present method.In order to satisfy the performance requirement better,the adjustment procedure for the damper parameters arranged in every layer of the structure is proposed.
