摘　　要：采用基于梁 -柱单元的非线性分析程序 ,对成都双流机场航站楼二典型柱面网壳 +支承柱这一整体结构在三种主要组合工况 (竖向对称荷载组合、竖向非对称荷载组合及风荷载组合 )作用下的承载性能进行了全过程追踪分析。结果表明 ,与单纯柱面网壳结构相比 ,柱面网壳 +支承柱这一整体结构的失稳路径单一 ,一般仅发生极值型失稳 ;其弹性极限承载力大大降低 。In this paper,the instability paths of two typical structural systems of Chengdu airport terminals,composed of single\|layer reticulated cylindrical shell and supporting system,were investigated by non\|linear analysis program based on Beam\|Column theory,considering the vertical symmetric load combination,vertical asymmetric load combination and wind load combination.The results indicate that,compared with the single\|layer reticulated cylindrical shell,both the ultimate load bearing capacity and the sensitivity of geometric imperfection of the whole structural system will decrease.
