| 摘 要： | 重庆江北国际机场航站楼主楼单索幕墙结构面积近10 000m2,并且一侧长度达到180m。其索网的支撑结构体系较柔,索网幕墙体系超长,给设计和张拉施工方案的制定都带来了较大难度。将屋面钢结构体系与幕墙结构体系整体建模,两者之间通过耦合实现水平联系,同步加载进行结构设计,以此考虑屋面钢结构对幕墙体系的影响。进行了超长幕墙结构体系跨越下部结构伸缩缝的受力分析,并得出由于柔性结构很强的变形适应能力,下部结构伸缩缝不会对幕墙结构体系产生破坏作用的结论。拉索幕墙的张拉方案必须与设计思路相互一致。对该超长单索幕墙张拉方案的原则也进行了介绍。

| Abstract: | The area of single-layer cable-net curtain wall of the main airport building of Chongqing Jiangbei International Airport is about 10 000m2,whose length for one side is 180m.The supporting structure system for the cable-net is flexible,and the curtain wall is over-length,which brings difficulties to the design and pre-stress construction plan.The whole model including roof steel structure and curtain wall system was established,and the relationship between roof and curtain wall was realized through horizonta... |
