［摘要］为满足建筑新颖而有特色的造型，贵阳201大厦采用支撑筒悬挂结构体系，分为主结构、子结构和悬挂桁架体系三部分。主结构为由12根钢管混凝土柱和偏心支撑组成的支撑筒；子结构为钢框架结构；悬挂桁架体系沿高度分3段设置，每段子结构设置6榀受力自平衡的悬挂桁架。分析表明：该结构体系各项相关参数满足规范要求；除因悬挂带来平面外挑和收进不规则外，其余各项均规则；风荷载作用下结构顶点加速度符合高钢规限值要求。稳定分析表明结构不会发生整体失稳。悬挂桁架节点分析表明在风荷载和罕遇地震作用不利工况下节点仍处于弹性受力状态，且悬挂桁架不会发生失稳。

Abstract:In order to have a novel and characteristic architectural design, the supported tube suspension structural system is adopted for Guiyang 201 Building which consists of three parts, the main structure, sub-structure and suspension truss. The main structure is a supported tube which is composed of 12 concrete filled steel tubular columns and eccentric braces. Substructure is a steel frame structure. Suspension truss system is set up by three segments, and each segment is set by six self-balanced trusses. The research shows that relevant parameters can meet code requirements. Apart from plane protrusion and setback caused by suspension, the rest is regular. Peak acceleration of the structure under wind load meets code limits. Stability analysis shows that overall instability does not occur. Suspension truss joint analysis shows that the joint still works elastically under the wind effect and rare earthquakes. And instability of the suspension truss does not occur.
Keywords:supported tube suspension system; supported tube; suspension truss; overall stability
