This paper investigates the optimal outrigger locations (OOLs) and optimal damping parameters (ODPs) for single-outrigger systems in high-rise buildings subject to earthquake and wind excitations. Three types of outrigger systems are considered: (1) the single-conventional/ordinary outrigger system (OR1); (2) the single viscous-damper outrigger system (OVD1); and (3) the single buckling-restrained-brace outrigger system (OBRB1). The paper proposes simplified models (SMs) for the top displacement, inter-story drift, and core base moment of single-outrigger systems subject to earthquake and wind excitations. The models are developed using a pseudo excitation method (PEM). The paper defines dimensionless parameters to characterize each of the three types of outrigger systems. Probabilistic models are developed to define the optimal outrigger locations as functions of such dimensionless parameters. Finally, additional probabilistic models are proposed to find the optimal damping parameters of OVD1 and OBRB1 as functions of the outrigger location, defined using the previously proposed models, and a dimensionless parameter capturing the relative stiffness of the system components.

本文研究了受地震和风激励的高层建筑中单支腿系统的最佳支腿位置 (OOL) 和最佳阻尼参数 (ODP)。考虑了三种类型的支腿系统：(1) 单一传统/普通支腿系统 (OR1)；(2) 单粘性阻尼支腿系统（OVD1）；(3) 单屈曲约束支撑支腿系统 (OBRB1)。本文提出了受地震和风激励的单支腿系统的顶部位移、层间漂移和核心基础力矩的简化模型 (SMs)。这些模型是使用伪激励方法 (PEM) 开发的。本文定义了无量纲参数来表征三种类型的支腿系统。开发概率模型以将最佳外伸支架位置定义为此类无量纲参数的函数。最后，提出了额外的概率模型来寻找 OVD1 和 OBRB1 的最佳阻尼参数，作为使用先前提出的模型定义的支腿位置的函数，以及捕获系统组件相对刚度的无量纲参数。
