| Abstract: | This paper presents the theoretical and model experimental studies of elastic buckling of single layer sphere grids shell.A finite element method program of elastic buckling of the structure was finished with consideration of large displacement behaviour.The analysis of the model structure was made by use of the program.The analysis results show that the analysis theory is reliable and the program is resultful. This paper has discussed this analysis theory and showed the further research direction. |
