摘　　要：广州南沙国际金融论坛永久会址为大型复杂建筑,屋盖长度长,立面构成体系多、传力复杂,屋盖和立面一体化设计,具有诸多结构设计难点。重点介绍了屋盖和外立面结构体系构成,屋盖包含大跨度桁架、正交网格梁以及下凹形采光顶,立面结构由单层索网结构、PTFE双层刚柔幕墙结构、UHPC刚性吊挂结构组成。对整体结构进行弹性分析,考察结构静力变形、动力特性以及关键支座反力。针对结构特点,对结构进行风荷载作用分析、温度作用分析,考察此类结构在两类荷载作用下的受力特点;对结构进行抗连续倒塌分析和弹塑性极限承载分析,结果表明结构具有足够的安全冗余,可以应对突发不利荷载的影响。Guangzhou Nansha International Financial Forum permanent address is a large complex building with large roof length,various facade composition systems and complex force transfer,and integration design of roof and facade,which has many structural design difficulties.The roof and facade structure system were mainly introduced.The roof consists of largespan truss,orthogonal grid beam and concave skylight roof.The facade structure consists of single-layer cable net structure,PTFE double-layer semi-rigid curtain wall structure and UHPC rigid suspension structure.The elastic analysis of the whole structure was carried out to investigate the static deformation,dynamic characteristics and the reaction of key bearings.For the structural characteristics,wind load action analysis and the temperature action analysis were carried out for the structure to investigate the mechanical characteristics of this kind of structure under the action of two types of loads.The continuous collapse resistance analysis and elastic-plastic limit bearing analysis were carried out for the structure.The results show that the structure has enough safety redundancy to deal with the impact of sudden adverse loads.
