武汉天河机场新航站楼设计中,采用后张有(无)粘结预应力混凝土技术有效解决了主体结构大空间、大跨度、相邻变跨度、大跨度悬挑和超大平面未设温度变形缝等关键技术问题,介绍了其预应力混凝土梁的计算分析和配筋设计,以及无粘结预应力地下室顶板的设计。为国内类似规模建筑的楼面设计提供了成功经验。 Wuhan Tianhe Airport Terminal Design, the use of post-Zhang (no) bonding prestressed concrete technology to effectively solve the main structure of a large space, large span, adjacent variable span, large-span cantilevered and ultra-large plane without temperature deformation of the seam And other key technical issues, the calculation analysis and reinforcement design of prestressed concrete beams and the design of unbonded prestressed basement roof are introduced. It has provided successful experience for the design of the floor of a similar scale building in China.
