| 摘 要： | 广交会工艺品交易中心玻璃光篷悬索支承结构由索桁架、受拉桁架、檩条(架)悬挑桁架及中心桁架组成。该工程结构分析时首先通过模态分析结构拓扑是否合理，同时建立了计算模型，考察结构几何非线性的强弱，设计中考虑了包括恒载、屋面活载、风载、地震荷载和温度荷载等荷载类型。在悬索结构成型和使用过程预应力张拉顺序及张拉力的大小可直接影响结构的安全性和适用性。确定张拉顺序为：张拉连系索→安装承重索→安装微调稳定索→放下悬吊重物。

| Abstract: | The suspended cable support structure used for the glass roof of handicrafts trade center in Guangzhou International Commodity Fair is composed of cable truss, tensile truss, purlin overhanging truss and center truss. Structural analysis is firstly carried out with modal to judge if the structural topology is rational; meanwhile, a calculation model is established and geometric non-linear behavior of the structure checked. The loads considered in the design include permanent loads, live loads on roof, wind, seismic and temperature loads and etc. In the process of installation and operation of the suspended cable structure, pre-tensioning sequence and magnitude may directly affect structural safety and usability. The determined sequence is as follows: tension tie cable, install load-bearing cable, erect adjustable cable and release suspended weight. |
