摘　　要：概要介绍了悬挂建筑结构的性质，提出悬挂比及悬挑比的概念。重点分析了中央核筒悬挂建筑结构的受力性能及一般计算原则。最后提出了悬挂结构的减振分析模型，表明悬挂建筑结构有良好的抗震性能。Central core tube suspended building structure is one of an important structural form in structural engineering.This paper introduces briefly the characteristics of suspension building structures,and proposes a new concept of suspension ratio which expresses the relationship between the suspension section area and the core tube section area.The main point of the paper is that the properties under external forces including the weight of structure,the actions of wind and earthquake,and a general calculating principle are discussed.Finally an analytical model for reducing the vibration of the structure is given.The results show that suspension buildings have advantage for resisting the action of earthquake or wind.

关 键 词：悬挂结构 悬挂比 受力分析 振动模型
