中文摘要：

在这研究，简化了数字模型被开发分析框架结构上的效果基于堆积组基础与粘弹性的 dampers (VED ) 装备了的土壤结构相互作用(SSI ) 。首先，一个单个 degree-of-freedom (SDOF ) 振荡器成功地被利用代替精力驱散结构考虑的 SDOF SSI 效果。相等的时期和系统的抑制比率随形式的紧张精力(MSE ) 的采纳用频率转移函数通过相似分析被获得技术。参量的分析被执行在 VED 的表演上学习 SSI 效果。然后平衡方程多，有就 SSI 效果而言的 VED 的 degree-of-freedom (MDOF ) 结构在频率领域被建立。把古典正常模式基于联合系统的上层建筑拥有的假设， MDOF 上层建筑是到通过公式推导由 MSE 技术的采纳承担在一个僵硬基础上的一套单个 SDOF 系统的 decoupled。数字结果证明建议方法有的优点然而，减少计算费用保留令人满意的精确性。此处建议的数字方法能就 SSI 效果而言提供 VED 的效率的快评估。

英文摘要：

In this study, simplified numerical models are developed to analyze the soil-structure interaction （SSI） effect on frame structures equipped with viscoelastic dampers （VEDs） based on pile group foundation. First, a single degree-of- freedom （SDOF） oscillator is successfully utilized to replace the SDOF energy dissipated structure considering the SSI effect. The equivalent period and damping ratio of the system are obtained through analogical analysis using the frequency transfer function with adoption of the modal strain energy （MSE） technique. Aparametric analysis is carried out to study the SSI effect on the performance of VEDs. Then the equilibrium equations of the multi degree-of-freedom （MDOF） structure with VEDs considering SSI effect are established in the frequency domain. Based on the assumption that the superstructure of the coupled system possesses the classical normal mode, the MDOF superstructure is decoupled to a set of individual SDOF systems resting on a rigid foundation with adoption of the MSE technique through formula derivation. Numerical results demonstrate that the proposed methods have the advantage of reducing computational cost, however, retaining the satisfactory accuracy. The numerical method proposed herein can provide a fast evaluation of the efficiency of VEDs considering the SSI effect.
