南京禄口国际机场T2航站楼结构设计

介绍了南京禄口国际机场T2航站楼的结构体系、设计方法和分析结果,着重阐述了密切配合建筑造型和空间需求确定钢屋盖结构体系的过程。提出了屋盖相连的分块混凝土结构整体分析的近似方法和非均布式预应力筋布置方式缓解大尺度混凝土结构温度应力的措施;基于显式积分方法进行了整体结构动力弹塑性分析,采用瞬态动力时程分析方法对屋盖钢结构进行了结构连续性倒塌分析,利用荷载-位移全过程跟踪技术对Y形柱进行了整体稳定性分析,最后对几个关键性节点的做法进行了介绍。

Structural design of Nanjing Lukou International Airport Terminal 2

Structural system,design principle,and analysis results of Nanjing Lukou International Airport terminal 2 were introduced.Process of closely incorporating with architectural form and space demand to determine the steel roof system was demonstrated.The approximate global analysis method for segmental concrete structures with continuous roof was proposed.Non-uniform prestress tendon layout to alleviate the impact of temperature stress to large scale concrete structure was studied.The elasto-plastic dynamic analysis to the monolithic structure by using explicit integral method was conducted.Progressive collapse analysis to the steel roof structure by using transient dynamic time history analysis was also conducted.The overall stability to the Y-shaped column by using load-displacement whole process tracking techniques was analyzed and several key joints were illustrated.
