摘要
上海浦东机场T2航站楼为一大跨空间钢结构,该结构体系复杂、规模大、构件形式新颖奇异、节点连接方式独特,理论分析、设计计算和连接构造难度均较大。对该结构体系的整体稳定性态进行了深入的分析,获得了该大跨结构在不同工况下的非线性整体稳定性态、失稳特征和稳定极限承载力,为该工程优化设计提供合理建议和可靠的设计验算数据,为类似大跨空间钢结构非线性分析提供了参考。
Shanghai Pudong airport T2 terminal is a large span spatial steel structure with complicated structure system,large scale, novel component shape and unique joint fashion. It is quite difficult in theoretical analysis, design and joint connection. The overall stability behavior of the structure system is analyzed. The nonlinear overall stability behavior, instability character and stability load-bearing capacity of the large span structure under different load cases are obtained. Reliable data for the optimal design of this structure are calculated. Reasonable suggestions are proposed. It is valuable for the nonlinear analysis for similar large span spatial steel structures.
