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。
In order to meet the new and unique architectural style, Guiyang 201 tower structure using the support system, divided into the main structure, substructure and suspension truss system of three parts. The main structure is a support tube composed of 12 concrete-filled steel tubular columns and eccentric supports; the sub-structure is a steel frame structure; the suspension truss system is divided into three sections along the height and each sub-structure is provided with 6 悬 self-balancing suspension truss. The analysis shows that all the relevant parameters of the structure system meet the requirements of the code. All the rules except for the plane outburst caused by the suspension and the irregularities received are all the rules; the acceleration of the structure apex under the wind load conforms to the requirements of the high steel gauge. Stable analysis shows that the structure does not suffer from global instability. Analysis of suspension truss nodes shows that the node is still under elastic stress under unfavorable conditions of wind load and rare earthquakes, and the suspension truss will not buckle down.
