［摘要］武漢天河國際機場新航空塔臺高115m，為國內(nèi)第一、世界第二高民用塔臺。該塔臺建筑造型新穎，為非對稱結構，高度高、截面尺寸小、頭重腳輕。結構設計中對這些建筑特征采取了針對性的措施，設置有擴大尺寸的地下室改善結構的整體抗傾覆不利的狀況；采用混凝土筒體增大截面抗側剛度；上部功能區(qū)采用鋼筋混凝土筒體+鋼結構的混合結構，最大限度減小上部功能區(qū)的質(zhì)量偏心，減小下部墻肢的受拉狀況；頂層控制室采用只設4根鋼柱的框架結構，以滿足視野開闊的要求。此外介紹了塔臺的風荷載、地下室及基礎、結構分析結果、筒體受拉以及上部鋼結構外伸體系，對類似項目有一定參考意義。

Abstract:The new aviation tower of Wuhan Tianhe International Airport is 115m high, which is the first domestic and the second tallest civil tower in the world. The tower has a novel architectural shape, an asymmetric structure, high height, small cross-section size, and light weight. In the structural design, targeted measures were taken for these architectural features, and an enlarged basement was installed to improve the overall anti-overturning ability of the structure.The concrete cylinder is used to increase the lateral stiffness of the cross section; the upper functional area is a mixed structure of reinforced concrete tube and steel structure, which minimizes the mass eccentricity of the upper functional area and reduces the tension of the lower wall limb. The frame structure with only 4 steel columns is adopt to meet the requirements of wide vision for the top control room. Besides wind load, basement and foundation, structural analysis results, tube tension and upper steel structure extension system were also introduced, which has certain reference significance for similar projects.
Keywords:Wuhan Tianhe International Airport； control tower; reinforced concrete tube; steel frame
