东莞市科技馆单层球面网壳设计与分析

Design and Analysis of Single-Layer Spherical Reticulated Shell of the Science and Technology Museum of Dongguan

介绍了东莞市科技馆单层球面网壳的设计过程 ,对网壳进行了线性稳定分析、几何非线性稳定分析以及考虑材料非线性的弹塑性稳定分析 ,并研究了网壳的大开孔和支座形式等因素对其极限承载力的影响 ,得出了一些可供工程实际参考的结论。

In this paper,the design procedure of single-layer spherical reticulated shell used in the Science and Technology Museum of Dongguan is briefly introduced. The eigen buckling analysis,the geometrical nonlinear stability analysis and the elasto-plastic stability analysis are conducted. In these analyses different models are used to reveal the influence of big holes and support conditions on the ultimate load of the structure. Several conclusions are presented at the end of this paper.
