The damped outrigger system, an improvement of the conventional outrigger system, can contribute to better vibration control in high-rise buildings through proper supplemental damping. Using a spectrum-analysis-based simplified model, the optimal seismic performance of single-viscous damper-outrigger system is investigated in this study. This simplified model is first calibrated by an ANSYS model via modal analysis and response history analysis. It is then used to perform numerous parametric analyses to investigate the influence of one factor on the optimal damped outrigger location and the damping ratio. Subsequently, a comprehensive dimensionless parameter associated with all the data from the previous single-parameter analyses is obtained and applied to a new set of parametric analyses for curve fittings. Optimal damped outrigger locations derived from the top displacement and the inter-story drift are finally fitted as functions of this dimensionless parameter.

阻尼支腿系统是对传统支腿系统的改进，可通过适当的辅助阻尼来改善高层建筑的振动控制。利用基于频谱分析的简化模型，研究了单黏度阻尼支腿系统的最佳抗震性能。该简化的模型首先由ANSYS模型通过模态分析和响应历史分析进行校准。然后将其用于执行大量参数分析，以研究一个因素对最佳阻尼支腿位置和阻尼比的影响。随后，获得了与来自先前单参数分析的所有数据相关的综合无量纲参数，并将其应用于曲线拟合的一组新参数分析。
