[摘要]乌鲁木齐地窝堡国际机场新建航站区工程换乘中心主体结构采用钢筋混凝土框架结构体系,设置少量剪力墙用于调整结构扭转刚度,屋盖为大跨度单层菱形交叉网格结构体系,由钢管混凝土柱和钢管摇摆柱支撑。设计采用了基础隔震技术和黏滞阻尼减震技术。结构计算分析结果表明:设防地震下减震系数小于0.4,隔震层以上结构的水平地震作用及相关抗震措施可以按降低设防烈度1度设计; 隔震设计显著延长了换乘中心结构的自振周期,降低了超长结构的温度效应,减小了结构的扭转效应。

Abstract:The main structure of the transfer center of new terminal area project of  Urumqi Diwopu International Airport adopts reinforced concrete frame structure  system. A small amount of shear walls were set to adjust the torsional rigidity of the structure. The roof adopts a large-span single-layer diamond-shaped cross grid structure system, which is supported by concrete-filled steel tube column and steel tube swing column. The base isolation technology and viscous damping technology were adopted in the design. The calculation and analysis results of the structure show that the damping coefficient  is less than 0.4 under the fortification earthquake, and the horizontal seismic action of the structure above the seismic isolation layer and related seismic measures can be designed to reduce the fortification intensity by 1 degree; the seismic isolation design significantly prolongs the natural period of the transfer center structure and reduces the temperature effect of the super long structure and the torsional effect of the  structure.

Keywords:Urumqi Diwopu International Airport; seismic isolation design; seismic isolation bearing; temperature effect; torsional effect
