摘要
上海科技馆建筑物形体中间有一非常显著、突出科技馆建筑鲜明个性的巨型椭圆形玻璃球体,其位置、造型和规模使之成为最具表现力的建筑中庭空间。因此,对科技城椭球体网壳结构的设计及稳定性分析就成为整个结构设计的关键。本文为类似铝合金单层网壳结构的设计提供参考。
In this paper, the design procedure of a huge single layer ellipsoidal dome in Science and Technology Museum of Shanghai is presented in detail. Using nonlinear finite element method,the egin buckling of this single layer ellipsoidal dome is analyzed and equilibrium loath is traced with regard to the initial geometric imperfection by cylindrical arc length method. Some valuable conclusions are obtained,which not only provide theoretic basis for reasonable design of the super high rise buildings,but also help to improve current design codes.
