GLOBAL STABILITY ANALYSIS ON SINGLE-LAYER RETICULATED CYLINDRICAL SHELLS OF CHENGDU AIRPORT TERMINALS

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，几何缺陷敏感性亦有所降低。

Abstract: 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.
