[摘要]烏魯木齊地窩堡國際機場新建航站區(qū)工程換乘中心主體結構采用鋼筋混凝土框架結構體系,設置少量剪力墻用于調整結構扭轉剛度,屋蓋為大跨度單層菱形交叉網格結構體系,由鋼管混凝土柱和鋼管搖擺柱支撐。設計采用了基礎隔震技術和黏滯阻尼減震技術。結構計算分析結果表明:設防地震下減震系數小于0.4,隔震層以上結構的水平地震作用及相關抗震措施可以按降低設防烈度1度設計; 隔震設計顯著延長了換乘中心結構的自振周期,降低了超長結構的溫度效應,減小了結構的扭轉效應。

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
