Stability Analysis of Steel Roof Structure of Shanghai Pudong Airport Terminal/Xu Chunli1,Luo Yongfeng1,Zhou Jian2(1 Tongji Univ.,Shanghai 200092,China; 2 East China Institute of Architectural Design and Research,Shanghai 200002)
Abstract: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 ana
lysis for similar large span spatial steel structures.
Keywords:large span spatial steel structure; nonlinear overall stability; instability character; loadbearing capacity
