科技馆球幕影院球壳力学分析

Mechanical Analysis of Spherical Theater of Technology Museum

本文通过结合省科技馆球幕影院的实际工程,对混凝土球壳进行了力学性能分析,并对结果进行了讨论。分析结果表明,球壳在风荷载作用下对洞口比较敏感,而初始几何缺陷对混凝土壳的稳定性影响很大;同时,下部支承条件对结构的承载力也有影响。

Combined with the Spherical Theater Of Technology Museum Project,the mechanical analysis of concrete shell were completed in this paper. The analytical results showed that the shell was sensitive to the holes under the wind load. Initial geometrical imperfections had a great effect on the structural stability. The substructure was observed to influence the bearing capacity of stability as well.
