［摘要］為滿足建筑新穎而有特色的造型，貴陽(yáng)201大廈采用支撐筒懸掛結(jié)構(gòu)體系，分為主結(jié)構(gòu)、子結(jié)構(gòu)和懸掛桁架體系三部分。主結(jié)構(gòu)為由12根鋼管混凝土柱和偏心支撐組成的支撐筒；子結(jié)構(gòu)為鋼框架結(jié)構(gòu)；懸掛桁架體系沿高度分3段設(shè)置，每段子結(jié)構(gòu)設(shè)置6榀受力自平衡的懸掛桁架。分析表明：該結(jié)構(gòu)體系各項(xiàng)相關(guān)參數(shù)滿足規(guī)范要求；除因懸掛帶來(lái)平面外挑和收進(jìn)不規(guī)則外，其余各項(xiàng)均規(guī)則；風(fēng)荷載作用下結(jié)構(gòu)頂點(diǎn)加速度符合高鋼規(guī)限值要求。穩(wěn)定分析表明結(jié)構(gòu)不會(huì)發(fā)生整體失穩(wěn)。懸掛桁架節(jié)點(diǎn)分析表明在風(fēng)荷載和罕遇地震作用不利工況下節(jié)點(diǎn)仍處于彈性受力狀態(tài)，且懸掛桁架不會(huì)發(fā)生失穩(wěn)。

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
